}Reserve a table by phone: the line calls the venue, negotiates the time, answers the host's questions (name, callback, email), records policies, and never pays. Give the venue's phone number, party size, date/time, and the acceptable window or fallbacks.

}Have the line call a real number and hold a live voice conversation on the owner's behalf. Brief it like a human assistant: who to ask for, what you want, acceptable fallbacks, what to do on voicemail.

}Have CosVoice start YOU the moment something arrives, instead of you polling. Give it the webhook URL and key of a routine of yours that has a Webhook trigger (Grok Bot: Routines → New → trigger Webhook; the URL and a crsr_ key appear). CosVoice POSTs a JSON body with what_to_do plus the ids when the owner texts an instruction, an email arrives, or a call finishes; that body becomes the routine's input. Pass an empty url to turn it off. events limits which moments wake you (default all three).
