![Synthflow tool permissions in the Claude connector](https://storage.googleapis.com/granular-changelog/doc-images/claude_cover.svg)

Synthflow's official **Claude** connector and plugin are now live. Use Synthflow's capabilities from Claude, Claude Code, or Cowork in plain language.

The **connector** links Claude to your workspace. The **plugin** adds guided call and prompt reviews. See the [guide](/anthropic) to get started.

## Phone numbers API: SIP registration

Phone numbers now support outbound SIP registration via the API. Set it when you [import a number](/api-reference/platform-api/phone-numbers/create-custom-number), or [update](/api-reference/platform-api/phone-numbers/update-phone-number) an existing one.
