## AI overview

Chat SDK adds a vendor-official Dial adapter for building bots that communicate through SMS, MMS, and iMessage on real phone numbers. Conversations are represented as Chat SDK threads, with support for media, inbound voice-call transcripts, standard message APIs, HMAC-verified webhooks, subscriptions, handlers, posts, and per-thread state.

## Source excerpt

Chat SDK now supports Dial with the new vendor-official adapter. Build bots that send and receive SMS, MMS, and iMessage on a real phone number, with bidirectional media and inbound voice-call transcripts. Replies use the standard Chat SDK thread and message APIs, with HMAC-verified webhooks and stable per-conversation threading. Each phone conversation becomes a Chat SDK thread. Texts and media arrive as messages on that thread, and when a voice call ends, its transcript appears there too. Subscriptions, handlers, posts, and per-thread state work the same as with any other Chat SDK adapter. Read the Dial documentation to get started. Read more
