Rosie answers a business phone and, on its larger plans, books appointments. CosVoice answers, takes the booking request, and also picks up the phone itself: callbacks, supplier calls, confirmations. Rosie includes more minutes at $49; CosVoice starts lower and does more kinds of work.

Yes. 7 days with 10 minutes of calls on a real number. You add a card to start and nothing is charged that day. On day 7 your card is charged $29 for Starter, and $29 each month after that, unless you cancel first. If the 10 minutes run out early, calls pause until the plan begins. Cancel in Settings in a few seconds. One free trial per person, and it needs a permanent email address.
Starter is $29 a month with 100 minutes of calls. Plus is $79 with 300 minutes. Pro is $199 with 1,000. Extra minutes are $0.25 each, rounded up per call. Every plan includes the number, the email address, and the assistant connection.
Yes. Any assistant that supports MCP connects with one paste: Grok Bot, OpenAI dots, Claude, ChatGPT, Cursor, and others. The steps for a dot are at cosvoice.com/integrations/openai-dots. Meta's Muse takes a different road, because it writes its own connector: you make an API key and Muse reads our published spec at cosvoice.com/openapi.json. The steps are at cosvoice.com/muse. Any of them can be woken by CosVoice if it has a webhook URL and a token. Developers also get a REST API and signed webhooks.
US and Canada numbers. A single call can run up to 10 minutes; the line wraps up politely before the limit. A line can be on three calls it placed and three calls it answered at the same time (one of each on the free trial), and it can place up to 60 calls an hour. If one more person calls while it is answering three, they hear a busy tone and can call back.
Free for 7 days with 10 minutes of calls. Then $29 a month unless you cancel.
