Thank you for sharing the details. To help troubleshoot your outgoing call issue on the BYO extension, could you please provide the exact "ended reason" or error message shown in the call logs for the failed outbound calls? This information will help identify the root cause and suggest the right solution.

Hi Muhammadu Bilal, To address call forwarding drops where the call disconnects immediately after initiating a transfer, follow these steps: 1. **Verify Vapi Forwarding**: - Use the Vapi API to get the call details and check the

endedReason

. - If

endedReason

is

"assistant-forwarded-call"

, the forwarding was initiated successfully by Vapi. If not, review your assistant settings. - Ensure

serverMessages

is correctly configured to avoid overriding Vapi's call control. Remove

"phone-call-control"

from

serverMessages

if present. 2. **Check Telephony Provider**: - Use the

phoneCallProviderId

from the Vapi call object and check the call logs in your telephony provider's dashboard for transfer-related errors. - For Twilio: [Twilio Call Logs](https://console.twilio.com/us1/monitor/logs/calls) - For Vonage and Telnyx, check their respective dashboards. 3. **SIP Transfers**: - If using SIP, download the PCAP file from Vapi and open in Wireshark. - Filter for

sip.Method == "REFER"

to verify if the transfer request was sent. 4. **Common Fixes**: - Ensure the destination number is valid and callable. - Check for any call blocking on the destination. - Review any custom SIP configurations if applicable. For detailed steps, please refer to the [troubleshooting guide](https://docs.vapi.ai/phone-calling/in-call-control/transfer-calls/debug-forwarding-drops). If you continue facing issues, verify your configuration and logs thoroughly as per the guide.
