We are using a Spain number through SIP trunking in VAPI to initiate calls. However, we are encountering a "SIP Trunking Failed" error specifically for Spain numbers. For US numbers, the configuration is working seamlessly without any issues.
Could you please provide support on this matter? We have applied the same configurations for both regions.

This is the call-id : 908bc5ea-4c89-4faa-8fcb-72174e6ee912

I'm sorry to hear you're experiencing issues with SIP trunking for Spain numbers. To assist you effectively, I'll need to gather a bit more information about your current setup. Could you please confirm if you have verified the following for your Spain number configuration:

1. The SIP URI is correctly formatted and includes the necessary credentials and domain.
2. The destination SIP address is correctly specified in the `sipUri` attribute within the `forwardingPhoneNumbers` array.
3. Your receiving system is properly configured to handle SIP REFER messages, as VAPI utilizes SIP REFER to transfer SIP calls.

Once you confirm these details, we can proceed to troubleshoot the issue further. If everything seems to be configured correctly, it might be necessary to look into the specific error message or logs to identify the cause of the failure. Please provide any additional error details or logs if available.

You can continue this conversation by mentioning me in the message.
