Solved: Intermittent Voice Calls

robert.cooley · ‎07-13-2012

I have a problem with intermittent voice call on the network. We have recently migrated to CUCM8 and have identified that calls through on gateway out of the 7 have one way voice conversations but not to all extensions. Some work fine.

I have checked that this activity is random on the isdn30.

We have changed the gateway, I/o card and Dsp's

Any help would be appreciated. .

Have you checked the call stats on the handsets when they get one-way audio ? Have you tried Wiresharking the calls ? I understand that this is random, but it's the only way you'll be able to trouble shoot this.

My gut feel, though, is it's a network/routing issue, rather than a CUCM issue.

Thank you for your response. We did actually find this issue was due to a default gateway. Weird as I would have thought all calls would have been affected.
