xAI's voice agent can now text you mid-call

Per a post on Threads, xAI's voice agent builder picked up post-conversation actions: outbound SMS, email, and API calls.

• Outbound SMS through Twilio numbers: the agent texts the person it's currently talking to, from an imported number, in the middle of the call. Meant for confirmations, links, and anything easier to read than to hear. • System variables in API tools: the caller's number gets passed into the request so the agent can pull up their account and hand back personalized data. • Post-call email notifications: the message goes to up to three recipients and includes call duration, the channel, and a link to the recording.

The announcement says emails have a minimum call length setting so short calls don't trigger notifications. We couldn't find independent confirmation of the update in press coverage or in xAI's own materials.
