About CosVoice
CosVoice gives an AI assistant a dedicated US phone number and email address for outbound calls, inbound call handling, and follow-up. Users can ask a connected assistant to place calls, forward unanswered calls to the line, or call and text the line from their own mobile. It can handle tasks such as restaurant reservations, appointment requests, vendor follow-ups, and callbacks, then provides written call summaries and transcripts in the line's history and connected assistant, with summaries sent by email. Assistants connect through a remote MCP server using OAuth, while developers can use a REST API and webhooks to build custom connections. Monthly plans include set amounts of call time, with additional minutes billed separately. CosVoice serves individuals, small businesses, and developers who want phone capabilities for an existing AI assistant.
