This is useful for building agent selection interfaces without fetching full agent configurations. - **Delete batch calls**: Added `DELETE /v1/convai/batch-calling/{batch_id}` endpoint for removing batch call jobs that are no longer needed. - **Branch filtering for conversations**: Added optional `branch_id` query parameter to conversation endpoints including `GET /v1/convai/conversation/get-signed-url`, `GET /v1/convai/conversation/token`, and `GET /v1/convai/conversations` for filtering conversations by agent version branch. - **Spelling patience configuration**: Added `spelling_patience` setting to turn configuration with values `auto`, `low`, `medium`, and `high`. Controls how long the agent waits before assuming the user has finished spelling something out character by character. - **Custom SIP headers for transfers**: Added support for custom SIP headers when transferring calls via REFER. Configure `custom_sip_headers` arrays on phone number transfer configurations and workflow phone nodes for advanced telephony integrations. - **WhatsApp accounts on agents**: Agent responses now include `whatsapp_accounts` array for viewing connected WhatsApp Business accounts. - **Zendesk integration support**: Added `zendesk_integration` to the `ConversationInitiationSource` enum for conversations initiated through Zendesk. ### Audio Output Formats - **Expanded format options**: Audio generation endpoints now support additional output formats including WAV family variants, new OPUS bitrate options, `alaw_8000` for telephony, and `ultra_lossless` quality preset. This applies to Text-to-Speech, Text-to-Dialogue, Sound Generation, Music, and Voice Design endpoints. ### Dubbing - **Expanded status values**: Dubbing project status now includes additional states for more granular tracking of dubbing progress. - **Source language**: The `source_language` field is now always returned when fetching a dub's metadata. ### SDK Releases #### Python SDK - [v2.31.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.31.0) -
