SpaceXAI updated its voice agent builder with a possibility to trigger post conversations action. The action can be an SMS, Email or an API call. 

> System variables in API tools - Pass the caller's number into an API request to fetch their account and give them personalized information.

> Outbound SMS with Twilio numbers - Text the active caller mid-call from an imported Twilio number, for confirmations, links, and anything easier to read than to hear.

> Post-call notifications via email - Email up to three people when a call ends, with duration, channel, and a link to the conversation. Set a minimum call length so short ones stay quiet.
