Best Business Phone Systems of 2026
There is no single best business phone system. A solo consultant, a Google Workspace office, a 200-seat contact center and an IT team that wants to run its own PBX all need different things. Here are the best picks by situation, based on each provider's public pricing and feature pages.
This page is published by Cannon VoIP, which is one of the providers compared. Every claim about other providers comes from their public pages, cited on each comparison page, and we included categories we do not win.
How we chose
We looked at US small and mid-size businesses. Costs are for a 5-user office, priced on each provider's plan that matches the same features, with month-to-month rates where offered. Public pricing and feature pages were checked in October 2026.
Cannon VoIP
Five extensions cost $170 a month with no added regulatory or E911 fees and no contract, versus about $180 to $195 for Ooma Pro Plus and $277 to $402 for Nextiva once matching features and fees are counted. Grasshopper, Quo and Google Voice cost less, but they do not list desk phones, a CRM or contact center tools.
Runner-up: Ooma. Ooma Pro Plus is $29.95 per user month to month, though taxes and fees are added and texting caps at 1,000 messages a month.
Cannon VoIP
Every $34 extension includes a built-in CRM, power dialer, wallboard, call queues, website chat, unlimited texting and AI transcription. The AI receptionist is $65 a month, or free at 10 or more users.
Runner-up: SpectrumVoIP. Its Everything plan puts most features in one tier, but texting and voicemail transcription are add-ons and the advertised rates are tied to term contracts.
Cannon VoIP
Month to month at $34 per extension with no regulatory, E911 or support-tier fees added to the bill.
Runner-up: Ooma. Ooma is also month to month with no annual contract, but taxes and regulatory fees are added on top.
Grasshopper
True Solo is $14 a month billed annually (about $18 monthly, third-party reported) for one user and one number, and Small Business covers unlimited users for $55 a month billed annually. Calling is app based, and desk phones are not listed.
Runner-up: Quo. Quo Starter is $15 per user billed annually or $19 monthly, with a 7-day free trial and free porting in.
Google Voice
Voice Standard adds $20 per user to an existing Workspace plan, about $100 a month for 5 users, and calls work right inside Gmail, Calendar and Meet.
Webex
Webex Suite hosts 200 attendees for up to 24 hours at $25 per user a month, Enterprise goes to 1,000, and Cisco Room, Board and Desk Series video devices work with it.
Runner-up: Zoom Phone. Zoom's Workplace bundles add full Zoom Meetings from $24 per user month to month, and Zoom can move a live call into a video meeting.
Webex
Webex for Government and Webex Calling are FedRAMP Moderate authorized, and Webex Calling holds ISO 27001 and SOC 2 Type 2.
Runner-up: Zoom Phone. Zoom lists SOC 2 Type 2, ISO 27001, HITRUST, FedRAMP Moderate and PCI DSS attestations.

8x8 routes WhatsApp, Facebook Messenger, email and chat to agents, adds workforce management and predictive dialing, and lists SOC 2 Type 2, ISO 27001, HITRUST and PCI DSS. Pricing is by quote, reported at $75 to $140+ per agent.
Runner-up: Nextiva. Nextiva handles WhatsApp and social messages on every plan, and its contact center adds predictive dialing and workforce management.
FreePBX
The software is free and open source and runs on your own hardware or any cloud server. Basic calling can cost about $60 a month in hard costs if you have the skills, skip the paid modules and do not count your time.
Runner-up: 3CX. 3CX has free editions, and an 8-call system for up to 40 users is $300 a year on Basic, plus a carrier and hosting.
Phone.com
Phone.com lists 24/7 phone support on all plans, plus live chat and tickets, starting at $18 per user billed monthly.

Common questions
What is the best business phone system for a small business?
It depends on what you need. For a solo user or app-only team, Grasshopper and Quo cost the least. For a 5 to 50 person office that wants desk phones, a CRM and contact center tools on one bill, Cannon VoIP ($170 a month for 5, month to month) and Ooma are the best value in our data.
What is the cheapest business phone system?
For one user, Grasshopper True Solo at $14 a month billed annually and Quo Starter at $15 are the lowest in our data. For 5 users, Grasshopper's Small Business plan at about $75 to $92 a month is the cheapest, though it is app based with no desk phones listed.
What hidden fees should I look for?
Many providers add regulatory recovery, E911 and USF fees on top of the advertised price, and several meter texting or international calls. Also check whether call recording, queues and CRM integrations are in your tier or sold as add-ons, and whether the low price requires an annual contract.
