Enable Phone Calls
Phone is $30/mo with included free minutes, then per-minute usage.
Turn on Phone Calls under Responsibilities / Channels. Phone is $30/month with the first 20 minutes free, then $0.50/min.
Assign or sync a phone number, confirm E.164 formats for test calls, and set business hours so open/closed status is accurate.
Test with a known number before routing your main line.
