Hi, we have enabled two remote sites in a CUCM 6.1.2 multiple site centralized model with 3825 GW running c3825-spservicesk9-mz.124-9.T7.bin and Unity Express 3.2.1 in a NME-CUE.
When the Service Engine is up local users of this gateway get metalized or cut voice. I've been able to point out an abnormal increase of max jitter using information from IP phones. Besides that, everything else looks normal. No E1 or ISDN Q.921 errors or flapping interfaces, no higher than normal CPU and memory usage.
I'm suspecting IOS needs some updating but I don't have SmartNet support to upgrade router myself to try so I'm contacting my share support Cisco partner for that, but I'd like to check if someone has seen this before or have any other idea to troubleshoot this.
Thanks a lot.
