CosVoice

CosVoice gives an AI agent its own phone line and email address. Each line is a real US phone number in the owner's area code plus an inbox, attached to one assistant such as a Grok Bot, ChatGPT, Claude or any agent that speaks MCP. The line answers calls as the assistant and runs an intake rather than taking a message, places calls on the owner's behalf for restaurant reservations, appointments and vendor callbacks, and sends a written debrief with a summary, outcome, details and transcript after every call. Owners can forward missed calls from their own mobile to the line, and CosVoice also offers the line to small businesses as an AI receptionist. Agents connect through a remote MCP server with OAuth 2.1 or an API key, a REST API and signed webhooks. Pricing is in US dollars and set by call minutes, and every plan includes the number, the email address and every integration. Starter is $29 a month for 100 minutes, Plus is $79 a month for 300 minutes and Pro is $199 a month for 1,000 minutes, with extra minutes at $0.25 each. A 7-day free trial includes 10 minutes of calls and needs a card, and it moves to Starter on day 7 unless cancelled. Small businesses that want their phone answered can also look at VeraDial, an AI receptionist and business phone line. People who want a personal assistant they text can look at Pally, and developers who want to connect agents to apps rather than to a phone line can look at Composio.
