I'm trying to initiate outbound calls but not recieving any. Tried with multiple webhooks to different phone numbers. I'm using vonage for telephony but I dont see any call logs there. I've checked over all my logs im pretty sure the problem is with vapi. https://cdn.discordapp.com/attachments/1439165720230498376/1439165720876286024/Screenshot_2025-11-15_at_00.07.05.png?ex=69198706&is=69183586&hm=6e368563f7a80f9abb53f7b731e07854acdb81e2dc7ca105705d08d1e9306499& https://cdn.discordapp.com/attachments/1439165720230498376/1439165721438453760/Screenshot_2025-11-15_at_00.07.24.png?ex=69198706&is=69183586&hm=1d25e83942552784ab4c58ef253cd57191c0414b1ffb2743ab96567788cad157&

Hi dehydrated, If you're experiencing issues with outbound calls dropping immediately after transfer, you can follow these steps to troubleshoot the problem: 1. Verify Forwarding Initiation: Use the Vapi API to check if the call forwarding was successfully initiated. You can do this by retrieving the call information using the call ID:

bash
   curl -X GET "https://api.vapi.ai/call/{call_id}" \
   -H "Authorization: Bearer YOUR_API_KEY" \
   -H "Content-Type: application/json"

2. Check `endedReason`**:** Look for the

endedReason

in the API response. -

"assistant-forwarded-call"

indicates successful initiation. If the call still drops after this, it often points to telephony provider issues. - Any other

endedReason

suggests a potential configuration issue. 3. Assistant Configuration: Ensure the

serverMessages

in your assistant's configuration doesn't include

"phone-call-control"

unless you have custom call logic, and

phoneCallProviderBypassEnabled

is

false

for Vapi-managed transfers. 4. Verify Call Logs with Provider: If the Vapi call shows it forwarded successfully, inspect call logs at your telephony provider (like Twilio, Vonage, or Telnyx) for errors using the

phoneCallProviderId

. 5. SIP-Based Issues: If applicable, use Wireshark to check SIP packets: - Filter for

"REFER"

packets to confirm whether the transfer request was sent. - Look for any error responses from the SIP provider in response to the REFER packet. 6. Check the Destination Number: Ensure the destination number has the correct format, includes the country code, and is capable of receiving calls without blocks. If setup issues persist, review these resources: - [Debugging Call Forwarding Drops](https://docs.vapi.ai/phone-calling/transfer-calls/debug-forwarding-drops) - [Call Ended Reasons](https://docs.vapi.ai/calls/call-ended-reason) This should help you identify and resolve the issue with your call forwarding setup.
