Hello, I have set up a phone number in telnyx and connected it with VAPI following the documentation provided. The call is working very well but when I ask the bot to forward me to an agent, it executes the tool transferCall succesfully and the call finishes. There is something left to configure for this to work? Thank you so much

@notatel Hello! I'm glad to hear that your call setup with VAPI is working well. If the call is ending after you attempt to transfer to an agent, it's possible that the SIP address for the agent's phone system may not be correctly configured in the

forwardingPhoneNumbers

array with the

sipUri

attribute. To ensure that the call is forwarded correctly to an agent, please check the following: 1. Verify that the

sipUri

is correctly specified in the

forwardingPhoneNumbers

array. It should point to the destination SIP address where the agent's phone system can receive the call. 2. Make sure that the receiving system is configured to handle SIP REFER messages, as VAPI uses SIP REFER to transfer SIP calls. 3. Ensure that there are no issues with the network or the receiving SIP server that might be causing the call to drop. If you've checked these points and the issue persists, it might be necessary to look into the logs or any error messages you're receiving for more detailed troubleshooting. If you need further assistance, please provide any additional details or error messages, and I'll be happy to help you resolve this issue.

I set in the phone number a normal spanish number +34 etc

@notatel you have to enable call forwarding in your telnyx account first and then try again.

Is enabled but seems configured to allow call forwarding to a specific number only https://cdn.discordapp.com/attachments/1314498852853645365/1315927105061785650/Captura_de_pantalla_2024-12-10_a_las_7.23.54.png?ex=6759301e&is=6757de9e&hm=674143560499845715aa693754b3de2ac7ab496b72bb61e7c4eb4dd83985510c&
