RingCentral Review 2026: Pros, Cons and AI Features
RingCentral does almost everything a business phone system can do. It also has some of the harshest contract and billing reviews in the category. Here’s the read from its plans page, Terms of Service, G2, Capterra and Trustpilot.
The quick answer: RingEX is a deep, reliable platform (calls, texts, video meetings, fax and a path to a contact center) with plans from $20 per user per month on annual billing. The weak spots are small texting allowances, AI features sold as metered add-ons, and contracts that auto-renew for the same term. If you mostly need calls answered and booked, Carly does that from one prompt in ChatGPT or Claude.
RingCentral review scorecard
| Category | Score | The short version |
|---|---|---|
| Feature breadth | 5/5 | Calls, texts, video meetings, fax, webinars and contact center options in one account |
| Call quality and reliability | 4/5 | RingCentral advertises 99.999% reliability. Reviewers mostly agree, with some dropped-call reports |
| AI features | 3.5/5 | Transcripts and summaries included. The AI Receptionist and ACE cost extra |
| Business texting | 3/5 | 25 to 200 texts per user a month by plan, carrier registration required, shared SMS inbox is an add-on |
| Ease of use | 3.5/5 | Capable apps, but reviewers describe a learning curve and dense admin settings |
| Contracts and billing | 2/5 | Same-length auto-renewal and a remaining-term payoff if you leave early |
| Support | 2.5/5 | The most common theme in 1-star reviews |
| Value for a small team | 3/5 | Fair per seat. Add-ons, fees and the monthly-billing premium stack up |
| Overall | 3.4/5 | A strong platform with a heavy commitment. Worth it when you use the breadth |
RingEX holds 4.2 out of 5 on Capterra across more than 1,200 reviews, and G2’s Fall 2026 reports ranked it #1 in VoIP Providers. On Trustpilot, RingCentral sits at 1.7 across nearly 2,000 reviews. People using the phones rate it well; people trying to change or leave their account don’t.
RingEX plans and pricing (US, September 2026)
| Plan | Annual billing | Monthly billing | What it adds |
|---|---|---|---|
| Core | $20/user/mo | $30/user/mo | Domestic calling, on-demand call recording, 100 toll-free minutes, 25 texts per user a month, video meetings, AI transcripts and summaries |
| Advanced | $25/user/mo | $35/user/mo | CRM integrations, multi-site, reporting, 1,000 toll-free minutes, 100 texts per user, AI Writer |
| Ultra | $35/user/mo | $45/user/mo | 10,000 toll-free minutes, 200 texts per user, RingCentral Webinar, historical and real-time analytics |
The add-ons and fees that change the real number:
- AI Receptionist (AIR): $39 a month as a RingEX add-on or $49 standalone, with 100 minutes, then $0.50 a minute billed in 30-second increments.
- AI Conversation Expert (ACE): from $60 per user per month.
- Business SMS Booster (shared SMS inbox, reply templates, compliance tools) at $25, and Call Queues Booster at $35. Both come in the Customer Engagement Bundle, priced by sales.
- Extra local or toll-free numbers: $4.99 a month each.
- Texting registration: carrier (TCR) registration is required, and RingCentral notes additional TCR fees may apply.
- Regulatory fees and taxes (Federal Universal Service Recovery Fee, E911, Compliance and Administrative Cost Recovery Fee) on top.
- Desk phone rental only with a multi-year contract.
Ten users on Advanced run $250 a month annual or $350 monthly, before AIR, texting add-ons or fees. The trial is capped at five users and texting is off during it, so SMS is the one thing you can’t test before buying. Full math in our RingCentral pricing breakdown.
Carly is free Zapier-style workflows; AI agents from $35/month.
What RingCentral does well
Breadth in one account. Calls, texts, video, fax and webinars under one login, a contact center (from $65 per user) to grow into, and native multi-site, extensions and desk phones.
Reliability at scale. RingCentral advertises 99.999% reliability, and G2’s Fall 2026 reports ranked RingEX #1 in four categories, including VoIP Providers and Cloud PBX Platforms. Capterra fans point to call quality and the apps.
AI basics are included. Every plan gets live transcripts, captions, call notes and summaries. Advanced adds AI Writer. Core also lists LLM plugins and MCP connectors.
RingCentral AI features in practice
AI Receptionist (AIR)
AIR launched in February 2025, and RingCentral says more than 11,800 businesses use it. It covers an AI phone menu with routing, appointment booking, lead capture and text follow-up. A May 2026 update added texting plus Shopify and Calendly booking. There’s a 14-day trial.
Model the meter. At 20 calls a day averaging three minutes, a receptionist handles about 1,320 minutes over 22 business days: roughly $610 in overage on top of the $39 add-on. Community reports from March 2026 also describe AIR interrupting callers and not ending calls after a booking. More in our RingCentral AI Receptionist review.
AI Assistant and ACE
The included AI Assistant covers transcripts, summaries and writing help. ACE is the sales-coaching layer: at $60 per user, a five-person sales team on Advanced annual pays $425 a month, versus $125 without it.
Carly answers, books callers on your team’s real calendars while they’re on the line, and logs every call to your CRM.
What RingCentral users complain about
Contracts that renew themselves
RingCentral’s Terms of Service say services automatically renew for the same length as the initial term unless either side gives notice at least 30 days before the term ends. One community post describes a contract that “renewed for 3 years automatically,” and recent Trustpilot reviews describe 2-year renewals.
The detail most buyers miss: RingCentral only has to give notice of a price increase 30 days before the term ends. That’s the same deadline as your non-renewal notice, so a higher price can arrive just as the window to leave closes.
Leaving early means paying the rest of the term
Terminate for any reason other than a material breach by RingCentral and you owe the remaining charges for the term, plus taxes and fees, within 30 days. One community post cites an “$1800+ early term fee.” Cancellation has to come from the admin or account owner, by phone or chat, and the account is disabled for 30 days before it closes. See our guide to canceling RingCentral.
Billing disputes
Trustpilot reviewers describe unexpected renewal charges and slow refunds, and disputes must be in writing within 30 days of the invoice. Capterra reviewers flag unclear 10DLC texting guidance and SMS features behind paid add-ons.
Support you have to fight to reach
Hard phone menus, slow email replies and quiet account managers dominate 1-star Trustpilot reviews. Capterra users score customer service 4.0: day-to-day help is fine, account and billing changes are where it breaks.
Complexity for a small office
A learning curve, outbound calls defaulting to the main company number, and occasional dropped calls.
Who RingCentral fits, and who is overbuying
RingCentral fits:
- Teams of 25 or more across multiple locations that need extensions, call queues and desk phones.
- Businesses replacing separate video meeting, webinar and fax tools.
- Support teams with a realistic path to a contact center.
You’re probably overbuying if:
- You’re a 2 to 10 person team that mostly needs one number, texting and missed calls answered.
- You text customers all day. 25 texts per user on Core runs out fast.
- You can’t commit to a term. Monthly billing costs $10 more per seat on every plan.
- Most of your calls end in “can I book a time?”
For a lighter texting-first app, Quo runs $15 per user on annual billing ($19 monthly) for Starter, $23 or $33 for Business and $35 or $47 for Scale. See Quo vs RingCentral and RingCentral alternatives.

Carly business setup prompt
Paste this into ChatGPT, Claude or any AI. It walks you through the rest.
Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.
# Connect Carly Teams to an AI app
> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.
MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)
## Setup
Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.
1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.
2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.
3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.
4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.
## Email, calendars and workflows
Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.Get started, or compare more in our AI answering service guide and best AI receptionists.
FAQ
Is RingCentral good for small businesses?
Yes, if you’ll use its breadth: multiple locations, desk phones, video and fax in one account. Teams under ten that mostly need one number, texting and answered calls often pay for features they don’t use, on an auto-renewing term.
How much does RingCentral cost per month?
RingEX is $20, $25 or $35 per user per month annual (Core, Advanced, Ultra), or $30, $35 and $45 monthly. AIR adds $39 a month with 100 minutes, then $0.50 a minute, and ACE starts at $60 per user, plus fees and taxes.
Does RingCentral require a contract?
Annual billing does, and it renews automatically for the same length unless you give notice 30 days before the term ends. Monthly billing costs $10 more per seat. Leaving mid-term means paying the rest of the term.
How do I cancel RingCentral?
The admin or owner contacts support by phone or chat, and the account is disabled for 30 days before it closes. Give non-renewal notice at least 30 days before the term ends. Full steps: cancel RingCentral.
Is RingCentral’s AI Receptionist worth it?
For low call volume, yes. At $0.50 a minute past 100 minutes a busy line adds hundreds a month, and March 2026 community reports describe it interrupting callers. If booking the right person is the job, Carly does that, set up from one prompt in ChatGPT or Claude.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
