CUCM to CUBE SIP trunk

[F1010]

Hi all

I have cucm and cube on my vm and I tried to make sip trunk between them but it's not going up however on cucm I already made sip trunk with ITSP and it is showing up and no change in the configuration between the trunk with cube and the trunk with itsp except the ip of the cube what could be the issue?

From the cube the reachability to cucm is OK and when I enable debug ccsip message I don't receive any traffic.

Please advise.

Thanks

To resolve the issue with the SIP trunk between CUCM and CUBE not going up, first ensure full network connectivity between CUCM and CUBE by using ping to confirm there are no IP routing issues or firewall blocks. Double-check the SIP trunk configuration on CUCM to ensure the IP address of the CUBE is correct, and verify that the SIP Trunk Security Profile and SIP Profile settings match those used for the ITSP trunk. On CUBE, confirm that it allows SIP connections from CUCM by verifying dial-peer configurations with the correct session target pointing to CUCM and checking voice service voip settings for allow-connections sip to sip. Since no SIP messages are observed in the debug output on CUBE, ensure the SIP traffic is reaching CUBE by monitoring network traffic or adjusting any intermediate network devices that might be dropping packets. If the issue persists, review both CUCM and CUBE logs for any error messages or misconfigurations.
