I imported SIP_Trunk phone number, it is working properly from Eleven labs web and through API.
It is failing using elevenlabs-mcp on Claude Desktop, mcp server is running normally however the "make_outbound_call" fails with the below error:
Error executing tool make_outbound_call: 'ConversationalAiClient' object has no attribute 'twilio_outbound_call'
In Claude prompt, I have already shared agent_id, to_number and agent_phone_number_id
