RingCentral vs 8x8 (2026): the transparent one vs the quote-only one

RingCentral and 8x8 are the two providers most likely to land in front of a mid-market buyer who has outgrown a starter phone app and wants one vendor to carry both everyday calling and a real contact center. They compete for the same seats, they both run a global voice network, and they both fold messaging, video, and analytics into a single desktop app. Yet they take opposite approaches to the one thing a buyer needs first: a price. RingCentral publishes three flat per-user tiers you can read in thirty seconds. 8x8 removed its public pricing in late 2023 and now quotes every deal individually, which means you cannot compare the two on cost without picking up the phone.

We wrote this to level that field. Below you will find RingCentral's real, confirmed 2026 rates, an honest account of what 8x8 charges based on the reported figures buyers see in quotes, and a feature-by-feature read on where each platform is genuinely stronger. Pricing in this category moves, and 8x8's especially is a moving target, so treat every dollar figure as a starting point and confirm a live quote before you sign anything.

How we compared these two

We priced every plan tier we could read, cross-checked the numbers against each provider's own pricing page first and reputable secondary reporting second, tested the desktop and mobile apps, and read the fine print on contracts, taxes, and add-on line items. For RingCentral that was straightforward, because RingEX lists Core, Advanced, and Ultra publicly. For 8x8 it was not, because the company shows named feature bundles with no attached prices, so we relied on the ranges real buyers report from their quotes and we flag every one of those figures as reported rather than confirmed. Where a number could not be verified, we say so instead of guessing. Our full methodology lives on the how we test page.

At a glance

Here is the fast read on the points that usually decide the purchase. RingCentral figures are its confirmed annual-commitment per-user rates as of mid-2026; 8x8 figures are reported estimates because the company does not publish prices.

Pricing and total cost

Start with what is knowable. RingCentral's RingEX runs three published tiers on an annual commitment: Core at $20, Advanced at $25, and Ultra at $35 per user per month as of mid-2026. Those are the headline annual rates; pay month-to-month and each climbs roughly 33 percent, so Core lands near $30 and Ultra near $45. Nothing about that is hidden, and you can build a budget from it before you ever talk to a rep.

8x8 is the opposite experience. The company stripped per-user prices off its website in late 2023 and moved everything to quote-only, so the plans you see on its site are named bundles, Unified Communications, Contact Center, and a broader CX tier, with no dollar figures attached. The numbers buyers actually report from their quotes put the entry unified-communications seat around $24 per user per month, a higher unified tier around $44, and contact-center seats climbing past $85 and into the low hundreds for full omnichannel CX. We label all of those as reported, not confirmed, because 8x8 will not stand behind a public number. The practical effect is that you cannot comparison-shop 8x8 the way you can RingCentral. You have to enter a sales cycle to learn the price, and the price you are quoted depends on your seat count, your term length, and how hard you negotiate.

The fine print matters more than usual with 8x8. Secondary sources consistently flag setup fees that can run from about $1,000 to $25,000 or more depending on how large and contact-center-heavy the deployment is, additional phone numbers at roughly $2 to $10 each per month, contact-center add-ons that lift the seat cost another 20 to 50 percent, and the possibility of 3 to 5 percent annual price increases if you do not negotiate a cap into the contract. RingCentral has its own upsell surface, a set of paid boosters like an AI Receptionist from $39 per month, a Business SMS Booster at $25, and a Call Queues Booster at $35, so its real per-seat cost can climb past the sticker too. The difference is that RingCentral's add-ons carry public prices and 8x8's setup and escalation terms surface only inside a quote. On both platforms, remember that taxes and regulatory fees typically pile another 15 to 25 percent on top of whatever you agree to.

Run the arithmetic on a real team and the transparency gap turns into a planning gap. Take a 25-person office that wants CRM integration and automatic recording. On RingCentral you can price it in your head: 25 seats of Advanced at $25 is $625 a month before tax, or roughly $720 to $780 once the 15 to 25 percent in taxes and fees lands, and you know that number today. On 8x8 the same 25 seats at the reported ~$24 unified-communications rate looks similar on paper at around $600, but you cannot bank on it, because the quote you receive folds in a setup fee you will not see until the proposal arrives and a renewal escalator you have to catch in the contract. Two providers can quote the same monthly seat cost and still deliver very different total cost of ownership over a three-year term once one side adds a five-figure implementation charge and annual increases. That is the real reason the pricing model, not just the price, belongs at the top of this comparison.

One more nuance on the annual-versus-monthly choice. RingCentral's roughly 33 percent monthly premium is a known, published penalty you can opt into for flexibility, which is genuinely useful if you are unsure about headcount or want to pilot before committing a year. 8x8 does not really offer a comparable low-friction monthly path; because everything is contracted, the flexibility you buy is negotiated into the term rather than toggled at checkout. For a business that expects to grow or shrink unpredictably, RingCentral's published month-to-month option is a quiet advantage that rarely shows up in feature charts but matters at signing time.

Setup and onboarding

These two aim at different ends of the effort spectrum. RingCentral is built to be stood up quickly by a small team without a project manager: you buy a published plan, port or provision numbers, assign extensions, and drive the setup through a self-service admin console with a large library of guides. A five-person office can be live in a day or two, and RingCentral offers a free trial so you can test the app before you commit a card.

8x8 is a sales-led motion by design. Because pricing is quote-only, onboarding almost always runs through an account team and, for larger or contact-center deployments, a formal implementation project. That is a strength if you are rolling out hundreds of seats and blended inbound-outbound routing, since you get hands-on help configuring queues, IVR flows, and supervisor tooling. It is friction if you are a ten-person company that just wants dial tone and a mobile app, because you are negotiating a contract and possibly paying a setup fee before your first call connects. The setup fees secondary sources cite, from four figures into the tens of thousands, are the tell: 8x8's onboarding is priced and scoped like an enterprise project, not a self-serve signup.

The porting step deserves care, because it is where switching cost usually hides for both providers, and the two run it very differently: RingCentral hands you a self-serve console to drive the move, while 8x8 folds it into a specialist-led implementation. We break down the paperwork, the realistic timelines, and the fee reality for each in the dedicated switching section below, so we will not duplicate it here beyond flagging that it is a line item you should scope, not assume.

Think about who actually does the work, too. RingCentral assumes a competent office manager or IT-adjacent person can configure auto-attendants, call groups, and user permissions from documentation. 8x8 assumes a project sponsor working alongside an implementation specialist, which lowers the internal skill you need but raises the coordination overhead and the timeline. For a lean team with no dedicated IT, that trade can cut either way: some small businesses love that 8x8 does it for them, others resent being routed into a multi-week enterprise onboarding for what they see as a phone system. Match the onboarding model to your appetite for either self-service speed or guided rigor before you let price decide.

Voice and video quality

Both providers run mature, carrier-grade voice networks and both market five-nines reliability, so on domestic call quality this is close to a wash for a typical office. The meaningful differences show up at the edges, in international reach and in how many faces you can fit on a single video call.

8x8 wins on international calling, and it is not subtle. Its entry unified-communications tier includes unlimited calling to roughly 14 countries, and the higher unified tier extends unlimited calling to around 48 countries. For a business with offices, suppliers, or customers spread across borders, that bundled global reach can quietly erase a large international-toll line item, and it is the single most compelling reason to shortlist 8x8. RingCentral has a strong global footprint too, but it leans more on paid international plans and add-ons rather than baking dozens of countries of unlimited calling into a mid tier.

Put a number on it and the gap gets concrete. A company that places even a few hundred minutes a month of calls into the UK, Germany, India, and Australia can watch per-minute international charges add up fast on a plan that meters them, and 8x8's higher unified tier folding roughly 48 countries of unlimited calling into the seat can turn a variable, unpredictable international line into a flat one. That predictability is worth as much as the raw savings to a finance team that hates surprise toll bills. RingCentral can absolutely serve international teams, but you are more likely to be pricing an international add-on or a per-country plan on top of the base seat, which means doing the math per corridor rather than trusting a single bundled tier. If your calling map is genuinely global, this is the dimension where 8x8's model was built for you.

8x8 also wins on raw video capacity. Buyers report its unified-communications tier supporting video meetings up to 500 participants, which comfortably covers company all-hands, town halls, and large training sessions without a separate webinar tool. RingCentral caps video at 100 participants on Core and 200 on Ultra, which is plenty for departmental meetings but short of 8x8's ceiling if you regularly gather the whole company on one call. If your video needs are ordinary team standups and client calls, that gap will never matter; if they are large-audience events, it matters a lot.

It is worth being precise about what that 500-participant number buys you, because participant caps are the most misread spec in this category. A 500-seat ceiling is not about your average Tuesday standup; it is about whether you can retire a separate webinar or events tool. Companies that currently pay for a standalone large-meeting product on top of their phone system are effectively double-paying for a capability 8x8 folds into the UC seat. RingCentral's 200-participant cap on Ultra covers the vast majority of internal meetings, and for the occasional larger event RingCentral steers you toward its webinar and events products, which is a separate line item. So the honest framing is not that RingCentral cannot do large meetings, but that 8x8 includes more of that headroom in the base seat, which is a cost story as much as a capacity story.

On the softer side of quality, both apps handle the fundamentals a modern team expects: HD audio, noise reduction, screen sharing, and mobile-to-desktop call handoff. RingCentral's app is the more mature generalist, with a polished desktop client and a deep settings surface that power users appreciate and casual users can mostly ignore. 8x8's app is competent and increasingly clean, and its strength shows when you cross into contact-center territory, where the same client surfaces supervisor and agent tooling that a pure UC app never needs. Neither is a weak link for daily calling; the differentiators remain international reach and meeting scale rather than raw call fidelity.

AI features

RingCentral has made built-in AI a core part of RingEX rather than a bolt-on, and importantly it starts low in the lineup. Core ($20) already includes a basic AI layer, transcription, real-time notes, and closed captioning, and the Advanced ($25) tier adds more capable generative AI such as SMS drafting. So you get usable AI on the entry plan and stronger AI one step up, without jumping to the most expensive tier. RingCentral also sells more specialized AI as paid add-ons, an AI Receptionist and an AI Conversation Expert among them, for teams that want to push further.

8x8's AI story is harder to pin down from the outside precisely because pricing and packaging are quote-only, but its intelligence features cluster around the contact-center side of the house: supervisor analytics, call monitoring, and the barge, monitor, and whisper tools that gate at the higher unified tier. That framing tells you where 8x8 invests, in agent and supervisor tooling for teams running phone support, rather than in everyday AI note-taking spread across every knowledge-worker seat. For a sales or support floor with supervisors coaching live calls, that is valuable. For a general office that just wants automatic call summaries on every desk, RingCentral makes that easier to buy and easier to price.

The monitor, whisper, and barge trio is worth decoding because it is the heart of 8x8's supervisor value and it has no clean RingEX equivalent. Monitor lets a supervisor listen to a live call silently, whisper lets them coach the agent without the customer hearing, and barge lets them join the call outright to rescue a difficult conversation. For a phone-support or sales team where call quality is the product, that live-coaching loop is a genuine capability, not a checkbox, and it is one of the clearest reasons a contact-center-leaning buyer leans 8x8. RingCentral surfaces this kind of tooling in its separate RingCX contact-center product rather than in RingEX, which is the recurring pattern between these two: 8x8 tends to bundle contact-center muscle closer to the core, RingCentral tends to sell it as an adjacent product.

The way to choose on AI is to ask where your AI value actually lands. If it lands on every knowledge worker, an account manager who wants their calls transcribed and summarized so they can skip note-taking, RingCentral's approach of putting a basic AI layer on Core and generative AI on Advanced spreads that value across the whole company at a published price. If it lands on a smaller, high-stakes group of agents and the supervisors coaching them, 8x8's contact-center-flavored intelligence is aimed exactly at them. Neither is objectively more advanced; they are pointed at different seats, and the right answer follows your org chart more than any benchmark.

Integrations

This is RingCentral's home turf. It carries the largest third-party integration catalog of the providers we track and treats that breadth as a headline selling point, with connectors for Salesforce, Zendesk, and a long tail of business apps that switch on at the Advanced tier. If your team lives inside a CRM and wants screen-pops, click-to-dial, and calls logged automatically against the right record, RingCentral simply gives you more native options out of the box, and its marketplace keeps growing.

8x8 is far from bare here: it integrates with the heavy hitters, Salesforce, Zendesk, and NetSuite among them, from its unified-communications tier, which covers the CRM and helpdesk stacks most mid-market teams actually run. The gap is at the margins and in the long tail. If your must-have connector is a mainstream CRM, both providers have you. If you need an unusual vertical tool or you want the widest possible marketplace to grow into, RingCentral's catalog is the deeper bench. Teams that need still more coverage sometimes cast wider, and our RingCentral vs Nextiva comparison is a useful next read if support reputation is also weighing on your shortlist.

There is a subtle gating detail buyers miss on RingCentral: those third-party CRM integrations switch on at Advanced ($25), not on Core ($20). So the true cost of a CRM-connected RingCentral seat is $25, not $20, and you should budget for Advanced from day one if screen-pops and call logging are the whole reason you are shopping. 8x8, by contrast, includes Salesforce, Zendesk, and NetSuite from its entry unified-communications tier, so there is no upgrade tax to unlock the mainstream CRM connectors. That flips the usual read: for a team whose only integration need is a big-name CRM, 8x8 may reach the finish line without a tier bump, while RingCentral asks you to step up to Advanced. The catalog is still deeper on RingCentral overall, but the entry-level CRM story is closer than the marketing suggests.

Support and reliability

Both providers market a financially-backed 99.999 percent uptime SLA, and that five-nines claim is genuinely a signature of 8x8's marketing, a platform built to keep contact centers running. On raw reliability, neither is the weak link for a typical business, and both run geographically redundant networks.

Customer-satisfaction scores are more mixed and worth reading carefully. RingCentral rates about 4.0 out of 5 on G2 across roughly 900 reviews, a solid score for an enterprise platform, but its Trustpilot sits near 1.8 across roughly 2,000 reviews, where billing and support complaints are a recurring theme. 8x8 lands more in the middle of the pack: around 4.2 on G2 across roughly 1,400 reviews, about 3.5 on Trustpilot, roughly 4.1 on Capterra, and 8.5 out of 10 on TrustRadius. Read those together and 8x8 looks like the steadier, less polarizing experience on public review sites, while RingCentral is a capable platform that clearly frustrates a meaningful slice of customers on billing and support even as its core service holds up. Neither is a runaway here; if support responsiveness is your top worry, you will want to press both on their SLA remedies and escalation paths during the sales process.

A word on how to read a 1.8 Trustpilot next to a 4.0 G2, because that spread confuses buyers. G2 skews toward business reviewers verified through work email, often mid-market and enterprise admins who evaluate the product on its merits. Trustpilot skews toward self-selected consumers, and phone-service Trustpilot pages in particular fill up with billing disputes and cancellation frustration, which drags scores down across the whole category, not just RingCentral. So RingCentral's low Trustpilot number is real signal about its billing and support experience, but it is not evidence the calls drop or the platform is unreliable. The fairer read is that RingCentral's product is strong and its commercial relationship, invoicing, contract changes, cancellations, is where the friction concentrates. 8x8's steadier spread suggests fewer of those sharp-edged commercial complaints, though its own quote-only model creates a different kind of friction earlier, at the buying stage.

Both providers back their uptime with a service-level agreement, and the practical question is not whether they promise five-nines but what happens when they miss it. Financially-backed SLAs typically credit you a portion of your bill against downtime, and the remedy terms, how outages are measured, what counts as covered, how you claim credits, live in the contract rather than the marketing page. This is exactly the kind of clause worth reading on any 8x8 quote and worth asking RingCentral to spell out in writing. Uptime marketing is nearly identical between the two; the enforceable remedy is where the real difference, if there is one, will be.

Which should you choose?

There is no universal winner, only the right fit for your size and use case. Here is how we would steer each band:

• 1 to 5 employees: RingCentral, and honestly you might want something even simpler. A tiny team can self-serve onto RingEX Core at a published $20 and be live fast, with no setup fee and a free trial to test first. 8x8's quote-only, sales-led motion is heavy machinery for five phones; the negotiation and possible setup fee are not worth it at this size.
• 6 to 20 employees: RingCentral for most, unless you are already an international-heavy shop. RingEX Advanced at $25 unlocks CRM integrations and stronger AI at a price you can see today. Consider 8x8 only if unlimited calling to many countries or 500-seat video is a real, recurring need.
• 21 to 50 employees: it depends on your calling map. If your team is domestic and CRM-driven, RingCentral's integrations and transparent tiers win. If you place heavy international volume or you are standing up a small phone-support team, 8x8's bundled global calling and contact-center path start to earn the sales cycle.
• 51 to 200 employees: genuinely a tossup that hinges on the contact center. If you are unifying UC and a real inbound/outbound contact center under one vendor, 8x8's welded UC-to-CX architecture and supervisor tooling are compelling, and at this scale a negotiated quote can beat sticker pricing. If you want breadth of integrations and published, predictable per-seat cost, RingCentral holds.
• 200+ employees: both are legitimate enterprise choices; run a formal bake-off. 8x8 leans in hard on international reach, five-nines SLA remedies, and a single-vendor UC-plus-contact-center story. RingCentral counters with the deepest app ecosystem and mature analytics. At this size you will get custom pricing from both, so decide on architecture and support terms, not the rack rate.

By use case: pick 8x8 if international calling, large all-hands video, or a tightly integrated contact center define your needs. Pick RingCentral if you want published pricing you can budget against, the widest integration catalog, or everyday AI on every desk. And if the idea of quote-only pricing bothers you at all, that discomfort is itself a signal pointing to RingCentral.

One decision rule cuts through most of this. Ask whether your center of gravity is the office or the contact center. If most of your seats are ordinary employees who make and take calls, want their meetings and messages in one app, and occasionally need a CRM screen-pop, you are an office, and RingCentral's published tiers, deep app catalog, and everyday AI fit that shape cleanly. If a meaningful share of your seats are agents on queues, supervised and coached, measured on handle time and service level, you are a contact center, and 8x8's welded UC-to-CX architecture, live monitoring tools, and bundled international reach were built for exactly that. Most businesses know which of those two they are within a sentence, and once you do, the winner between these two stops being a coin flip.

Switching and number porting

The scariest part of changing phone providers is not learning a new app; it is trusting that your business number, the one on every invoice, business card, and Google listing, survives the move. It does, and on both RingCentral and 8x8 the port itself is almost always free. What differs is who drives it and how the timeline plays out, and those differences track the same self-serve-versus-guided split that runs through this whole comparison.

The paperwork is nearly identical on both sides, because it is dictated by the carriers, not the platform. You submit a Letter of Authorization (LOA) that proves you own the numbers, plus a recent bill from your current carrier so the account name, service address, and account number match to the digit. A single transposed account number is the most common reason a port stalls, so the practical advice on either provider is to copy those details straight off your latest invoice rather than from memory. You also decide whether to port your main number alone or the whole block of direct-dial numbers at once; porting everything together is cleaner but slightly slower to validate.

On RingCentral, porting is a self-serve motion. You provision temporary numbers the day you sign so you can start testing calls immediately, then submit the port request through the admin console and track its status there. RingCentral keeps your old service running until the port completes, so the cutover is a clean flip rather than a gap, and you point your temporary configuration at the real numbers once they land. For a small office, a single main-number port commonly clears in about one to two weeks; a larger block of numbers or a stubborn losing carrier pushes it toward three or four. Because it is self-driven, the pace depends partly on how quickly your admin responds to any validation kickback.

On 8x8, porting rides inside the specialist-led implementation. An assigned coordinator collects your LOA and bill, submits the port, and manages the back-and-forth with your old carrier on your behalf, which is genuinely less work for you but means the timeline is paced by the project schedule as much as by the carriers. During the cutover 8x8 sets up temporary forwarding so calls keep reaching your team while the numbers migrate, and larger contact-center ports are staged deliberately to avoid dropping live queues. Plan for the same rough one-to-four-week window, with bigger and more complex deployments landing at the longer end because they are validated in phases.

The fee reality is where the two diverge most. RingCentral does not charge a standing porting fee for standard business numbers, so switching to it is close to a zero-dollar line item beyond your seats. With 8x8, the port itself is typically free too, but it arrives wrapped in the same quote-only implementation that can carry a setup fee, so the honest move is to ask the rep to itemize porting and implementation separately on the proposal. If you are weighing 8x8 mainly against another guided, contact-center-first provider rather than RingCentral, our Nextiva vs 8x8 comparison walks through the same switching mechanics from a different angle. Whichever way you lean, treat the port as a scheduled project step, not an afterthought: confirm the temporary-number or forwarding plan up front so no customer ever hits a dead line during the flip.

The real 12-month cost

Sticker price and annual price are different animals, and the gap between them is exactly where these two providers reward or punish you. To make it concrete, take a realistic mid-market scenario: a 25-seat team that needs CRM integration and call recording, the same profile we used earlier, and follow it across a full year rather than a single invoice.

On RingCentral, that CRM requirement forces the Advanced tier at $25 per seat, because third-party CRM connectors switch on there rather than on Core. Twenty-five seats at $25 is $625 a month, or $7,500 a year at the base. Now fold in the add-ons a real deployment tends to grab: say a Call Queues Booster at $35 a month and a Business SMS Booster at $25 a month for the teams that need them, another $720 across the year. There is no porting fee to recover and no setup charge. Add the 15 to 25 percent that taxes and regulatory fees pile on, and the all-in twelve-month number lands roughly in the $9,500 to $10,300 range, every dollar of which you could forecast on day one from published rates.

On 8x8, the same 25 seats at the reported ~$24 unified-communications rate looks cheaper up front: about $600 a month, or $7,200 a year at the base, and CRM connectors like Salesforce and Zendesk are included at that entry tier, so there is no upgrade tax to unlock them. The catch is the one-time layer. Even a modest 8x8 implementation commonly carries a setup fee in the low thousands, call it $2,000 to $3,000 for a deployment this size, and if you want the higher unified tier for supervisor tooling you are closer to $44 a seat, which alone would push the annual base past $13,000. Stay on the entry tier, add the same 15 to 25 percent in taxes and fees, and fold in a ~$2,500 setup charge, and year one lands roughly in the $10,800 to $11,600 range. Crucially, that setup fee is a year-one-only cost: strip it out and 8x8's year-two run rate can dip below RingCentral's, which is why a multi-year 8x8 commitment can quietly win on total cost even when year one looks higher.

Cheapest over 12 months for this 25-seat, CRM-plus-recording scenario: RingCentral, once the 8x8 setup fee is counted, and it is the safer forecast because every input is public. But the ranking flips over a three-year horizon if 8x8's negotiated seat price holds and that setup charge amortizes away, so the right lens is your intended term. Buy for one year and value predictability, RingCentral. Commit for three and you are willing to work a quote, and 8x8 becomes a live contender on pure dollars. The trap to avoid on either side is anchoring to the monthly seat figure alone; the boosters, the tier that actually unlocks your must-have feature, and the one-time fees are where the real twelve-month number hides.

Alternatives worth a look

If neither of these is quite right, three others come up often. Nextiva is the support-and-simplicity pick, with the lowest entry price of the mainstream providers and a standout satisfaction record, a strong option if 8x8's quote-only friction and RingCentral's billing complaints both give you pause. Dialpad is the AI-first choice, bundling live transcription and automatic call summaries from its entry tier for teams that want voice intelligence as a core feature rather than an upsell. Ooma Office is the small-office value play, with flat, contract-free pricing that is the antithesis of 8x8's sales-led model for teams under roughly twenty seats.

Frequently asked questions

Is RingCentral or 8x8 cheaper?

RingCentral is easier to price and usually cheaper to start. As of mid-2026 RingCentral publishes RingEX Core at $20, Advanced at $25, and Ultra at $35 per user per month on an annual term. 8x8 removed public pricing in late 2023 and is quote-only, so its figures are reported estimates: roughly $24 per user per month at the entry unified-communications tier, about $44 at the higher unified tier, and $85 or more for contact-center seats. A heavily negotiated large 8x8 deal can beat sticker pricing, but you cannot confirm that without a quote, and 8x8 deals often carry setup fees. Verify current pricing with each provider before you buy.

Why doesn't 8x8 show its prices?

8x8 removed per-user pricing from its website in late 2023 and moved to a quote-only, sales-led model. The plans on its site are now named bundles, Unified Communications, Contact Center, and a broader CX tier, with no dollar figures attached. In practice you have to talk to a sales rep to learn what a seat will cost, and the number depends on your seat count, contract term, and negotiation. That is the biggest practical difference between the two providers, since RingCentral lists every RingEX tier publicly.

Which has better video meetings, RingCentral or 8x8?

8x8 has the higher video ceiling. Buyers report its unified-communications tier supporting up to 500 participants, versus RingCentral at up to 100 on Core and up to 200 on Ultra. If you run large all-hands or training sessions, 8x8's capacity is a real advantage. For ordinary team meetings and client calls, both are more than enough and the difference will not matter.

Which is better for international calling?

8x8, clearly. Its entry unified-communications tier includes unlimited calling to roughly 14 countries and the higher unified tier extends that to around 48 countries, all bundled into the seat. RingCentral has a strong global network but relies more on paid international plans and add-ons than on bundling dozens of countries of unlimited calling into a mid tier. If cross-border calling is a big part of your bill, 8x8 can save real money.

Can I keep my phone number if I switch to RingCentral or 8x8?

Yes, and in most cases the port itself is free on both. You keep your existing business numbers by submitting a Letter of Authorization and a recent carrier bill, then RingCentral or 8x8 coordinates the cutover with your old provider while your current line stays live. RingCentral leans on self-serve porting through its admin console; 8x8 typically runs the port for you as part of a specialist-led implementation. Expect roughly one to four weeks for business-number ports, and see the switching section above for the paperwork, the temporary-forwarding step, and where a setup fee can appear on an 8x8 quote.

Does RingCentral or 8x8 include a contact center?

8x8 folds a contact center directly into its product lineup, with dedicated Contact Center and CX bundles that build on its unified-communications tier under one vendor and one contract. RingCentral's contact center, RingCX, is a separate product rather than a RingEX tier, so you buy it alongside RingEX. If a tightly integrated UC-plus-contact-center package is your goal, 8x8's architecture is the more unified path; if you mainly need business phone service, RingEX stands on its own.

Which is more reliable?

Both market a financially-backed 99.999 percent uptime SLA and both run redundant, carrier-grade networks, so reliability is close to a tie for a typical business. On public review sites 8x8's satisfaction scores are steadier across G2, Capterra, and TrustRadius, while RingCentral rates about 4.0 on G2 but near 1.8 on Trustpilot, where billing and support complaints recur. Reliability itself is a wash; the support and billing experience is where RingCentral draws more criticism.

Do I have to sign a contract with either one?

RingCentral's headline prices assume an annual commitment; you can pay month-to-month for roughly 33 percent more without the annual term. 8x8 is contract-based and quote-driven, typically with annual or multi-year terms and discounts for prepay, and its contracts may include annual price increases of about 3 to 5 percent unless you negotiate a cap. Read the term and escalation language carefully on any 8x8 quote before signing.

Bottom line: RingCentral wins on transparency, integration depth, and everyday AI at a price you can read today, while 8x8 wins on international calling, large-scale video, and a unified contact center for buyers who can work within a quote-only sales process.
