Nextiva vs RingCentral vs 8x8 for Small Business Phones (2026)
Three cloud phone platforms compared on plans, call features, Microsoft Teams and CRM integration, Yealink handsets, AI, contract terms and support, plus what an integrator adds.
Nextiva, RingCentral and 8x8 give a small business cloud calling, meetings and messaging per user per month. They differ in how they publish prices, how they reach Microsoft Teams, which AI features are included, what the contract asks of you, and how much of the installation is left to you. This guide compares them, then explains what an integrator adds.
What is UCaaS, and what is this comparison based on?
UCaaS: Unified Communications as a Service, a cloud phone system that bundles calling, voicemail, video meetings, team messaging and call analytics into one subscription per user, delivered over your internet connection instead of a phone server in your telecom room. Nextiva, RingCentral and 8x8 are UCaaS platforms; phones, network and installation are separate decisions.
Disclosure: Telxpress installs and supports Nextiva as a partner and installs Yealink handsets on all three platforms. We read each vendor's own pages the same way, as of October 2026, and link to them so you can check our reading.
How do the plans and prices compare?
Nextiva publishes three small-business tiers: Core at $15 per user per month on annual billing, shown against $23 month to month; Engage at $25, shown against $50; and Scale at $75. Core covers voice, SMS, video meetings, call routing and team chat; Engage adds a toll-free number with minutes, advanced reporting and live chat; Scale adds AI transcription and summary and skills-based routing (Nextiva).
RingCentral publishes two RingEX tiers with prices and two bundles without. Core is $20 per user per month paid annually, or $30 monthly, with unlimited domestic calling, on-demand call recording, 100 toll-free minutes, 25 SMS per user per month, HD meetings for up to 300 participants and the AI Virtual Assistant. Advanced is $25 paid annually, or $35 monthly, and adds CRM integrations, multi-site support, reporting, 1,000 toll-free minutes and 100 SMS per user. The AI Customer Engagement bundles, which include the AI Receptionist, are quoted (RingCentral).
8x8 does not publish per-user prices. Its pricing page presents 8x8 Work (calling, meetings and messaging), 8x8 Engage, 8x8 Contact Center and 8x8 for Microsoft Teams, each with a capabilities list and a request-a-quote button (8x8).
Three cautions. The low figures assume annual billing; both vendors show the monthly price as the crossed-out number. Taxes and fees are added on top: RingCentral's disclaimers list a Federal Universal Service Recovery Fee, an E911 fee, a cost recovery fee and state and local taxes, and note that unlimited calling covers the US and Canada only (RingCentral). And call recording, texting allowances (Nextiva 100, 500 and unlimited per user by tier; RingCentral 25 and 100) and toll-free minutes separate the entry tiers more than calling features do (Nextiva).

How do they connect to Microsoft Teams and your CRM?
There are three routes into Teams. Microsoft describes Operator Connect as connecting Teams Phone to the public telephone network through a Microsoft-certified operator that manages the carrier side while your administrator assigns numbers in the Teams admin center; it requires Teams Phone licenses (Microsoft). Direct Routing, the older route through the provider's own equipment, also needs Teams Phone licenses; an embedded app puts the provider's calling inside Teams without them.
Nextiva Business Phone for Microsoft Teams uses Direct Routing and requires a Microsoft 365 E5 license or E3 with the Phone add-on, which Nextiva does not sell; Teams appears as an add-on on Nextiva's pricing table (Nextiva Teams). RingCentral for Microsoft Teams offers an embedded app, Direct Routing and early-access Operator Connect (RingCentral Teams). 8x8 Voice for Microsoft Teams requires a Phone System license per user for the Teams dial pad to appear and lets users have a desk phone, a Teams client or both (8x8 Voice for Teams); 8x8 Operator Connect requires a Teams Phone Standard license, assigns numbers inside the Teams admin center and includes only a number, with no 8x8 user-level features (8x8 Operator Connect).
CRM integration follows the same tiering: Nextiva sells Salesforce, HubSpot and other CRMs as an add-on (Nextiva), RingCentral includes CRM integrations from Advanced (RingCentral), and 8x8 lists integrations without itemizing them on its pricing page (8x8). Ask what the integration does with your CRM: screen pop, click to dial, automatic call logging, or all three.
Which Yealink phones work with each platform?
RingCentral's store lists Yealink desk phones from the T33G to the T87W, W76P and W79P Pro cordless phones and CP925 and CP965 conference phones; the T33G shows at $118 to buy or $5 a month to rent, and rental requires a multi-year contract (RingCentral phones, RingCentral). Nextiva lists the T33G at $100 up to the T87W at $300, or a monthly fee, and says you can keep your existing phones (Nextiva phones). 8x8 documents reusing Yealink phones that are a supported model with a factory-installed device certificate, and accommodates phones not bought from 8x8 on a commercially reasonable effort basis (8x8 Yealink).
Teams phones are a different device class: they register to Teams, with the platform behind them through Direct Routing or Operator Connect. Microsoft's certified list includes the Yealink MP52 E2, MP54 E2, MP55 E2, MP56 E2 and MP58 E2, certified to October 15, 2030, the MP54, MP56, MP58 and CP965 to August 15, 2028, and the MP66 W (Microsoft). If staff live in Teams, buy the Teams phone; if they live in the platform's app, buy the SIP phone.
What AI features do you get, and what do you still need?
All three sell AI in layers as of October 2026. Nextiva includes AI transcription and summary on Scale and sells the XBert AI Receptionist as an add-on (Nextiva). RingCentral includes its AI Virtual Assistant in Core and sells the AI Receptionist from $39 and Conversational Intelligence from $60 (RingCentral). 8x8 places AI-enabled self-service in Contact Center and conversational intelligence in 8x8 Engage, both quoted (8x8). The honest limit: a platform AI receptionist is a feature your office configures and maintains. An integrator-run agent such as Donya takes an extension on whichever platform you choose, is trained and tested by our team and hands calls back with a warm transfer; see AI receptionist services compared for which model fits.
What are the contract terms and support like?
Nextiva states cancel anytime and 24/7 phone, email and chat support on all plans (Nextiva). RingCentral discounts up to 33% for annual payment, limits its trial to five users and two desk phones returned within 21 days, and ties phone rental to a multi-year contract (RingCentral). 8x8's terms arrive with the quote (8x8). Whatever the platform, ask five questions before signing: term length, automatic renewal, price increases at renewal, early termination cost, and how your numbers are released if you leave.
What does an integrator add to a cloud phone system?
The platform runs the calls. The integrator makes them work in your building, on any of the three.
- Network readiness. Nextiva's guidelines call for 100 kbps per concurrent call, under 150 ms of latency to its servers, under 15 to 20 ms of jitter, hardwired Cat5e or Cat6 for phones, quality-of-service rules, no double NAT and SIP ALG disabled (Nextiva guidelines); Microsoft adds that quality of service belongs on every network segment and that Wi-Fi is not necessarily designed for real-time media (Microsoft). We test the connection, configure the firewall and switches and set the voice VLAN first.
- Cabling and power. Every desk phone needs a certified drop and a PoE switch port; our structured cabling team does this before cutover.
- Handset selection and staging. We match models to roles, confirm each against the platform's supported list and stage the phones so every desk works on day one.
- Number porting. Federal rules require carriers to complete a simple port within one business day and a non-simple port within four business days unless a longer period is requested, and ports involving interconnected VoIP are intermodal ports under the same rule (47 CFR 52.35). Multi-number business ports are usually non-simple, so we gather account details and the customer service record first.
- Parallel run and testing. The new system runs beside the old one while we test every call path, the after-hours flow, the emergency address on each line and the handoff to any AI agent.
- Training and cutover. Short sessions on the phones and the app, and a quiet day for the switch.
- One number afterward. When something breaks, you call us and we open the ticket with the platform or carrier.
Key takeaways
- Nextiva and RingCentral publish entry prices that assume annual billing; 8x8 quotes. Compare the tier you would actually buy, with add-ons, taxes and fees.
- Call recording, texting limits and toll-free minutes separate the entry tiers more than calling features do.
- All three reach Microsoft Teams by different routes; Direct Routing and Operator Connect need Teams Phone licenses, an embedded app does not.
- Network, cabling, handsets, porting and the parallel run are the same work on any platform, and they decide whether cutover day is quiet.

Questions
Questions this article answers
Which is cheapest for a small business: Nextiva, RingCentral or 8x8?
On list price as of October 2026, Nextiva's and RingCentral's entry plans are close, with the lower figure requiring annual billing, and 8x8 quotes rather than publishing prices. The cheapest plan is rarely the cheapest system once you add call recording, CRM or Teams add-ons, handsets and taxes. Price the plan you would actually use at your user count.
Do Nextiva, RingCentral and 8x8 work with Microsoft Teams?
Yes, in different ways. Nextiva and 8x8 connect through Direct Routing, which needs a Microsoft Teams Phone license per user, and 8x8 also offers Operator Connect. RingCentral offers an embedded Teams app, Direct Routing and early-access Operator Connect. Nextiva lists Teams as a paid add-on. Check the license you hold before comparing prices.
Can we keep our Yealink phones if we switch platforms?
Often, yes. RingCentral and Nextiva sell Yealink desk phones for their services, and 8x8 documents reusing existing Yealink phones that are a supported model with a factory-installed device certificate, on a reasonable-effort basis. Check the exact model against each vendor's supported list, and budget for replacements where firmware or certificates rule a phone out.
How long does it take to move our numbers to a new phone provider?
Federal rules require carriers to complete a simple port within one business day and a non-simple port within four business days unless a longer period is requested. Ports with many numbers or complex call routing usually count as non-simple, and the real schedule is set by paperwork accuracy and the old carrier, so plan for weeks end to end.
What does an integrator add if the phone platform is cloud-based?
The platform runs the calls; the integrator makes them work in your building. That means checking the network and cabling, PoE switches, quality-of-service and SIP settings, choosing and staging handsets, submitting the port with correct account details, running old and new systems in parallel, training staff, and being the one number you call. Platforms sell licenses; integrators own the outcome.
