My outbound calls using the Zadarma number are failing.
Hello Support Team,
I am experiencing a persistent issue where my Vapi number, sourced from Zadarma, receives inbound calls successfully, but all outbound calls fail.
I have performed extensive troubleshooting and require assistance checking the SIP logs, as the problem appears to be a final rejection from the Zadarma side.
Here are the details of my setup and troubleshooting steps:
Credential ID (The one that fails): aa20fed9-32c6-4b3b-898d-b3fef49c83a3
Credential Name: Zadarma-NoPlus
SIP Account Type: Main Zadarma SIP Account (PBX has been disabled).
Authentication Used: Main SIP Login (850561) @ sip.zadarma.com.
Troubleshooting Status:
Authentication Fixed: The Vapi Private Key is confirmed to be working.
Trunk Creation Fixed: The SIP Trunk Credential (aa20fed9-32c6-4b3b-898d-b3fef49c83a3) was successfully created and is linked to the phone number.
Number Format Tested: I have tested two versions (outboundLeadingPlusEnabled: true and false). The current linked version is false.
Request for Logs:
Please review the SIP logs for the most recent failed outbound call attempt from my number using the Credential ID aa20fed9-32c6-4b3b-898d-b3fef49c83a3.
We need the exact SIP rejection code that Zadarma is sending back (e.g., 403 Forbidden, 603 Declined). This is the last piece of information required to complete the fix.
Thank you for your help!
