User story
As an integrator, I want to post messages, calls and transcripts from our own channels into Conversations and let the AI answer, so that a smart speaker or our own phone system works like any built-in channel.
Problem / context
We run a smart speaker in hotel rooms and our own SIP system. There is no API to create a conversation on a custom channel, hand it to the AI employee, or store an external call with its full transcript.
Acceptance criteria
  • Create/append messages on a custom channel and receive the AI reply (sync or webhook).
  • Store external calls with recording link and full transcript as call activities.
  • Contact matching by E.164.
