I have a multi-site, multi-cme deployment.
CME versions 7.x
Site A: CME/CUE
Site B: CME/CUE
Site C: CME - uses Site B CUE
Among other things :), intermittently, calls are failing to VM on calls directed to Site C: but fwd to Site B:
Calling Number = 313 (Site B:)
Called Number = 777
call-forward noan *400 timeout 3 (3 for testing, 14 live)
Ext. 400 resides on Site B:
Ext direct-to-VM number is *400
When setting call-fwd all *400 I am unable to repeat the issue
When setting cfwd-noan *400 I will hear ring busy sometimes.
voice service voip
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
no supplementary-service h450.3
ephone-dn 55 dual-line
call-forward noan *400 timeout 3
I have attached output showing the output of deb ccsip messages. Note the disconnect cause code on the bad call. The good call was placed one minute later.
So, I guess the best question is...how to troubleshoot disconnect cause 41?
