OpenPhone (now Quo) review 2026: business VoIP phone features, pricing plans, AI call tools, pros, cons, FAQs and the best alternatives compared.
OpenPhone is a cloud-based business phone system founded in 2018 by Daryna Kulya and Mahyar Raissi and headquartered in San Francisco. It was built as a modern replacement for legacy desk phones and PBX systems, letting small teams set up business phone numbers that work through an app rather than physical hardware.
In late 2025 the company rebranded to Quo, expanding its focus toward AI-powered business communication while retaining the same underlying phone-system product. The two names describe the same company and platform, with existing OpenPhone customers migrated to the Quo brand.
The platform's signature feature is the shared phone number and shared inbox, which lets multiple team members call, text, and see conversation history from one business line, much like a shared team email inbox. It also includes AI call summaries and transcripts, an AI voice agent (Sona) that can handle routine incoming calls, and automatic call recording.
Additional features include auto-attendant phone menus, group calling and call transfers, voicemail transcription, and native integrations with HubSpot and Salesforce, making it a common choice for sales and customer support teams that need calling built into their CRM workflow.
OpenPhone uses per-user, tiered subscription pricing with a discount for annual billing. Starter costs $15/user/month billed annually (or $19/user/month billed monthly) and covers core calling, texting, and voicemail transcription.
Business costs $23/user/month annually (or $33 monthly) and adds AI call summaries, CRM integrations, and phone menus, while Scale costs $35/user/month annually (or $47 monthly) and adds AI call tagging and dedicated onboarding support. All plans include a 7-day free trial with no credit card required.
