Allo is a cloud business phone system built around an AI receptionist that answers, routes, and summarizes every call in real time. It records and transcribes conversations, drafts post-call emails and texts, and pushes structured notes straight into the CRM so reps do not have to log calls manually. Built for sales, support, and service teams, Allo bundles unlimited calling and texting, an AI-powered IVR, and a power dialer for outbound campaigns into one flat per-user price. It integrates with tools like HubSpot, Salesforce, and Zapier, making it a fit for teams that want a phone system that already speaks CRM.
Quo, rebranded from OpenPhone in September 2025, is a VoIP-based business phone system that gives teams shared numbers, calling, and SMS/MMS messaging in one collaborative inbox. Multiple teammates can see and respond to the same business number's calls and texts, with routing rules to direct incoming contacts to the right person. Quo layers an AI agent called Sona on top of the phone system to answer calls automatically, transcribe conversations, and summarize them, along with call recording and analytics. It is used mainly by startups and small businesses that need a professional, multi-line phone presence without deploying a traditional PBX, and it integrates with common CRMs like HubSpot and Salesforce on its higher tiers.
