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.

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.)

Cannon VoIP

RingCentral

Pricing & contract

$34/extension/month flat, all-in: unlimited domestic calling and texting included. No long-term contract: month to month.

Core $20/user/mo, Advanced $25, Ultra $35 (annual billing); plus separate regulatory and E911 fees. Annual contracts with early termination fees.

Add-ons & hidden fees

None. One flat rate per extension: no regulatory surcharge, no E911 fee, no CRM upcharge.

Compliance/Administrative Cost Recovery Fee and E911 fee on every invoice. AI Receptionist ($39–49/mo) and AI Conversation Expert ($60/user/mo) are separate paid add-ons.

Contract lock-in & termination fee

None: month-to-month. Leave anytime with no early termination fee.

Annual and multi-year contracts carry an early termination fee: BBB complaints document cases equal to 100% of the remaining contract value, with auto-renewal unless cancelled 30+ days before term end.

What's included

Call transcription and SMS included on every extension, every tier.

Core plan caps SMS at 25 messages/user/month and excludes call recording; both require the Advanced tier or higher.

Setup & onboarding

We handle every step of onboarding and set your team up for success, then call us anytime during business hours to add, change, or fine-tune any feature, big or small.

Self-serve admin portal built for IT-staffed organizations; feature access depends on which tier you're on.

Customer support & reliability

Standard support Mon–Fri, 9 AM–5 PM; if a system is down or it's urgent, a real person is reachable 24/7, no ticket queue, no support tier to unlock.

Reviewers describe inconsistent support quality; BBB complaints document early termination fees equal to 100% of remaining contract value, and contracts auto-renew unless cancelled 30+ days before term end.

Integrations

Microsoft Teams, Google Workspace, Zoho, HubSpot, Odoo: GoHighLevel coming soon.

330+ integrations in its app gallery (Salesforce, HubSpot, Zendesk, and more), but CRM integrations require the Advanced tier or higher.

International calling

$0.25/min to common countries, $1.75/min to less-common countries, rare/high-cost destinations quoted separately.

Not included on any RingEX plan: a separate International Calling Bundle runs ~$14.99/user/month for landline coverage in ~50 countries. Mobiles and anything outside the bundle are billed per-minute, reaching $0.50/min or more to high-cost destinations like the Philippines.

Hardware & BYOD

Bring your own desk phone if it's on our compatibility list, or get our VoIP-6 ($198) or an ATA adapter ($99). We never rent or lease equipment: it's 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: RingCentral's app ecosystem and global reach can make sense for large, IT-staffed enterprises. For most small and mid-size businesses, Cannon VoIP's flat $34/extension covers what RingCentral spreads across tiers and add-ons, with no contract to sign.
