Is there a firewall between Cisco IP Phones (or CUCM) and the Huawei PBX? Can you attach SDL logs from CUCM for a specific call?

There is no firewall between both system,can you please tell me how to take SDL logs from CUCM

The Cisco CallManager logs are needed: How to Collect Traces for CUCM 9.x, 10.x and 11.x

First make a call and then gather CallManager logs for the last xx minutes.

Hello bro!, are you using a CUBE? it´s just that i see the following

CUCM 10.222.0.11

IP Phone 10.222.0.115

direct INVITE to "213.34.194.102"

Dear Alexis,

There is no CUBE in between,this is only connection between CUCM TO Huwaei PBX

Please try to enable MTP (Media Termination Point) checkbox in Trunk Configuration settings on CUCM. This helped me.
