Exotel joins Twilio and SIP for telephony; agent transfers gain workflow nodes

ElevenAgents

• Exotel telephony integration: Added Exotel as a first-class telephony provider alongside Twilio and SIP trunking. New Exotel outbound call endpoint (POST /v1/convai/exotel/outbound-call) initiates outbound calls via the Exotel Connect API with agent_id, agent_phone_number_id, to_number, optional conversation_initiation_client_data and optional telephony_call_config. Exotel phone number create, list, get and update schemas are available, and exotel is added to TelephonyProvider, conversation initiation source and transfer result enums.
• Workflow-aware agent transfers: AgentTransfer now allows a nullable agent_id so transfers can stay on the current agent, adds optional node_id to start at a specific node in the destination workflow, and only requires condition. Successful transfer_to_agent tool results can include nullable to_node, aligning transfers with workflow-node targets.
• Agent test repeat runs: Run tests on the agent accepts optional repeat_count (integer, 1–20, default 1) to run each test multiple times. When repeat_count is greater than 1, responses include bucketing_status and result_groups for grouped summaries. Unit test create, update and summary schemas add optional conversation_initiation_source so tests can simulate a specific channel.
• Conversation filtering: List conversations adds optional workflow_node_entered_id (string) to filter conversations that entered a given workflow node. Text search conversation messages adds optional topic_ids (array of strings) to filter by topic IDs assigned during topic discovery.
• Agent versioning query parameters deprecated: enable_versioning on create agent and enable_versioning_if_not_enabled on update agent are marked deprecated. All agents are versioned and these parameters are ignored.
• Procedure compiler mode: Removed append from ProcedureCompilerMode.

Workspaces

• Revoke API key: Added revoke API key endpoint (DELETE /v1/workspaces/api-keys/revoke) with required api_key_name query parameter to revoke a workspace API key by name. This endpoint is destructive and requires additional account permissions, even though the documentation is public. Contact your ElevenLabs representative to enable it for your account.
• Resource access disclosure: Resource access response models add optional access_source (creator, explicit, workspace_default, workspace_admin) so clients can disclose why a user has access to a shared resource.

Speech to Text

• Larger upload limit: Convert speech to text now accepts audio and video files up to 5.0GB, increased from 3.0GB.

Dubbing

• hCaptcha support: Dub a video or audio file request body adds optional hcaptcha_token (string) for bot protection on dubbing project creation.
• Zip render format: RenderType adds zip alongside existing output formats such as mp4, aac, mp3, wav, aaf, tracks_zip and clips_zip.
