Chat SDK now supports Dial via a new vendor-official adapter, enabling bots to send and receive SMS, MMS, and iMessage on a real phone number with full bidirectional media and inbound voice-call transcripts.
Every phone conversation maps to a Chat SDK thread. Texts, media, and post-call voice transcripts all land on that thread. Subscriptions, handlers, posts, and per-thread state behave identically to any other adapter, so the integration cost is low for existing Chat SDK users. Webhooks are HMAC-verified and threading is stable per conversation.
The implementation details in the Dial documentation are worth reading closely, specifically how voice transcripts get appended to the same thread as SMS exchanges. That unified data model has real implications for bot memory and context management.
