OpenPhone (Quo)

OpenPhone, rebranded as Quo, is a business phone system with Sona AI built into the core product. The AI agent answers calls 24/7, asks follow-up questions to understand what the caller needs, and integrates smoothly with your CRM to pull and update customer information. It's positioned as a phone system first rather than a standalone voice builder.

This fits businesses that are replacing traditional phone services or augmenting their existing lines with AI. Unlike standalone voice tools, you get the complete phone infrastructure, so there's minimal integration work and your team can start using it like a regular phone system immediately.
