What CosVoice is
Gives an AI assistant such as a Grok Bot, Claude or ChatGPT its own US phone number and email address. It answers the calls you miss, places calls you ask for, such as booking a table or taking a contractor's quote, and sends a written summary after each one. A small business can brief the same line as its front desk. Plans are sized by call minutes a month, and extra minutes are billed per minute.
