Cannon VoIP vs. Ooma

Ooma Office is a budget-priced small-business phone service with three tiers and honest month-to-month billing. Cannon VoIP is one flat rate with everything on it. The differences live in the tier ladder and the caps.

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, with a main number plus a direct number for every extension (6 numbers) in the price.

Ooma

~$180–195/month

Matching what $34 includes means the top tier, Pro Plus, since call queues, CRM integrations, and AI transcripts all live there: 5 × $29.95 = $149.75 list. Ooma bills taxes, regulatory recovery, and E911 fees on top, charges that typically add 20–30% to US VoIP invoices at average usage, putting the real total around $180–195/month. And even then parity is not quite available at any price: texting caps at 1,000 messages per month for the entire account (250/month on Pro), where Cannon's texting is unlimited on every extension.

Pricing & contract

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

Essentials $19.95, Pro $24.95, Pro Plus $29.95/user/month, billed month to month with no annual contract; taxes and regulatory fees are added on top of advertised rates.

Add-ons & hidden fees

Month to month, like us. Credit where due: no contract on either side of this table.

What's included

Call transcription and SMS included on every extension, every tier. Queues, auto attendants, voicemail transcription, recording: included.

Tier-gated. Essentials has no desktop app and no texting; call recording starts at Pro; call queues, CRM integrations, HIPAA mode, and AI transcripts require Pro Plus.

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. Businesses within about an hour and a half of DFW Airport get free on-site installation.

Self-serve setup designed around Ooma's own hardware and app, with support lines for help along the way.

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.

Standard vendor support channels by phone and chat.

Integrations

Microsoft Teams, Google Workspace, plus 11 CRM integrations included: Zoho, HubSpot, Salesforce, Dynamics 365, GoHighLevel, Zendesk, Freshdesk, SugarCRM, Odoo, Housecall Pro, CallRail.

CRM integrations are gated to the Pro Plus tier; the catalog is smaller than the big UCaaS platforms.

International calling

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

Unlimited calling includes Canada, Mexico, and Puerto Rico, a genuine plus; other international destinations bill per minute.

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.

Sells its own IP phones and analog-friendly hardware outright, and supports a limited BYOD list.

Bottom line: Ooma's sticker prices are lower and its month-to-month terms are honest, which is more than most of this industry manages. The catch is the ladder: the features most businesses actually run, queues, CRM logging, transcripts, texting at real volume, live on the top tier with account-wide caps and fees stacked on top. If you would land on Pro Plus anyway, compare that all-in number against one flat rate that never caps your texting.
