Hi @Vapi @Vapi Support Bot I’m using Genesys to transfer calls to Vapi via SIP, and it was working fine until recently. Now, I’m facing an issue where the assistant selector API isn’t being called at all. Instead, I’m getting the message “phone number not found”, which is odd since I haven’t changed any configuration on my end. I’ve verified that I’m sending everything correctly from Genesys, the SIP address I’m using is: +61286247112@9cf4efae-dae9-472a-bb5c-851ffe362e0f.sip.vapi.ai This follows the correct format as per the Vapi documentation. Could you please help me investigate and resolve this issue?

Thank you for the details. To help troubleshoot, could you please confirm if the phone number +61286247112 is still registered and active in your Vapi dashboard, and associated with the correct SIP trunk? Sometimes this error occurs if the number is missing or unlinked in Vapi, even if nothing changed on your Genesys side. Let me know what you find!

yes its still registered in vapi dashboard in phone numbers section i have verified it multiple times and the trunk too is setup correctly and i am transfering correctly to +61286247112@9cf4efae-dae9-472a-bb5c-851ffe362e0f.sip.vapi.ai

Thank you for confirming the phone number and SIP trunk setup. To help narrow this down, have there been any recent changes to your SIP trunk provider settings, network/firewall rules, or IP allowlist that could affect inbound SIP routing to Vapi? Even small changes can sometimes cause the "phone number not found" error if Vapi's servers are unable to receive the SIP INVITE. Let me know if anything has changed on that front!

Please look into this @Vapi team

Hey! To help track down this issue, could you share: \- The call ID \- When exactly this happened (the timestamp) \- What response you expected to get \- What response you actually got instead This would really help us figure out what went wrong!
