Cannon VoIP vs. RingCentral

RingCentral is a large, feature-rich UCaaS platform built for global enterprises. Cannon VoIP is a flat-rate, no-contract phone system built for small and mid-size teams. Here's how the two actually differ.

The short version
With Cannon VoIP$170 a month for 5 users, all-in, with a built-in CRM, website chat, power dialer and live wallboard included, and no contract.
With RingCentralAbout $595 to $620 a month for the same setup, with the CRM, contact center and queue tools sold as higher tiers, separate products or add-ons.

Same 5-person setup. A very different bill.

Put the same five people on the same features and the gap is hard to miss: $170 a month all-in at Cannon VoIP, about $595 to $620 at RingCentral. These are included with every $34 Cannon VoIP extension, while RingCentral sells them as a higher tier, a separate product or an add-on:

  • Built-in CRM. RingCentral has no built-in CRM; its CRM integrations start on Advanced.
  • Website chat in the same portal. In RingCentral's lineup, website chat is part of the RingCX contact center, from $65/agent/month.
  • A power dialer for outbound campaigns. RingEX has none; outbound campaigns need the separate RingCX product.
  • A live queue wallboard with listen, whisper and barge. RingCentral puts whisper and barge on Advanced and up, and live queue reports in a $35 Call Queues Booster add-on.
  • Automatic call recording on every extension. RingCentral's Core tier records on demand only; automatic recording starts on Advanced.

5-user scenario: what you'd actually pay per month

Cannon VoIP
$170/month
5 extensions × $34, all-in. No regulatory fee, no E911 fee, no support-tier fee: unlimited domestic calling and texting, AI call/voicemail transcription, and CRM integration all included.
RingCentral
~$595–620/month
Cannon VoIP has no annual commitment, so this uses RingCentral's real month-to-month rate: 5 × Advanced ($35/user month-to-month, for CRM + unlimited domestic calling/texting) = $175, plus RingSense AI transcription/conversation intelligence at $60/user × 5 = $300, a $475 base. Independent analyses report real invoices commonly landing 20–35% above list once the Compliance & Administrative Cost Recovery Fee, E911 fee, and likely SMS overages (Advanced caps texting at 100/user/month, below typical usage) are added, pushing the real total to roughly $570–640/month. (Advanced drops to $25/user only if you prepay a full year.)

Moving from RingCentral is built in

Cannon VoIP has migration tools in the portal, and our team guides the move for free:

  • How your setup comes across. Live import straight from your RingCentral account using app credentials, and your menu wording comes across without re-recording.
  • Keep what your callers hear. Optional discovery calls ring your old system and record what its menus say, so the wording, or the original recordings, can come across.
  • Nothing changes until you approve it. Review a plan with counts before anything is applied; an import report lists anything that could not come across.
  • No gap in service. Your RingCentral service keeps taking calls until your numbers port, at $15 per line, usually the next business day.

Contact center tools
A wallboard with live queue stats, where supervisors can listen, whisper or barge into live calls, plus a power dialer for outbound campaigns that only calls between 8am and 9pm in the lead's local time.
Whisper and barge on Advanced and up. Live queue reports need the Call Queues Booster add-on ($35). No power dialer in RingEX: outbound campaigns use the separate RingCX product.
Call screening & 911
Call screening shows each caller's name and reason word for word as they speak, before you answer, and AI screening rules send calls you never want to voicemail without ringing. A 911 address is registered on each number and checked with 911 systems, each building can be a 911 site, 911 calls from the mobile app send the phone's location, and people you choose are alerted when anyone dials 911.
Callers can announce their name before the call connects.
Connect your own AI assistant
Connect Claude, ChatGPT, Gemini or any Model Context Protocol (MCP) assistant, choose which areas it can reach, and high-risk actions wait for a person to approve them.
MCP connectors for ChatGPT, Claude and other AI assistants are included on all tiers.
Platform ownership
We wrote our own phone software and apps, and we run our own servers and switching from an undisclosed location in Fort Worth, with two backup regions; customer data is stored only in the US and is never shared or sold; only three outside companies for voice and texting; most feature requests ship in under four weeks.
Builds and runs its own cloud platform (RingEX). It also licenses that platform to other brands, including Avaya Cloud Office, Mitel and Vodafone.
Desktop apps (incl. Linux)
Windows, Mac and Linux desktop apps, a browser phone with nothing to install, plus Android and iPhone. The Linux app is our own and officially supported, like every other Cannon VoIP app.
Official desktop app for Windows and Mac. A Linux app exists only as a RingCentral Labs community project, which RingCentral says is not an official product and has no official support.
Hardware & BYOD
Bring your own desk phone if it's on our compatibility list, or get our VoIP-6 ($198, with 10% off at 25 phones and 15% off at 75) or an ATA adapter ($99). Most other standard SIP phones can connect with basic SIP credentials, without the portal's remote management. We never rent or lease equipment: phones and adapters are yours to keep, purchased outright.
Supports BYOD and offers desk phones through a recurring "Device-as-a-Service" rental subscription rather than a one-time purchase, you never own the hardware. Reported mid-range phone rental runs about $15/device/month; renting past ~13 months (198÷15) costs more than buying our VoIP-6 outright ever would, and you still wouldn't own it.

Bottom line: Apples to apples, five users with matching features cost $170 a month at Cannon VoIP, all-in, and about $595 to $620 at RingCentral. That is roughly $425 to $450 less every month, over $5,000 a year, and the $34 Cannon VoIP extension still includes a built-in CRM, website chat, a power dialer and a live wallboard, with no contract to sign.
