ElevenAgents

  • SIP logs: SIP signaling logs are now available for SIP trunk calls in conversation history and phone number settings. Logs include the SIP call ID, phone numbers, addresses, transport, message direction, raw messages and errors to help debug call setup and routing issues.
  • Knowledge base document updates: New API to list indexed (RAG) chunks for a document. Documents can also be edited in place: rename the item and, for text-based documents, update the body without re-uploading the file. (File-based documents still use the existing replace-file flow where applicable.)
  • SMS conversation metadata: Added SMS support to conversation metadata with SMSConversationInfo, sms as an authorization method and twilio_sms as a conversation initiation source.
  • Agent configuration updates: Added background music configuration schemas, alerting monitor configuration, 2D layout fields, widget file upload configuration, and new LLM options gpt-5.4-mini, gpt-5.4-nano, gpt-5.4-mini-2026-03-17 and gpt-5.4-nano-2026-03-17.
