I've got 2 users having a line cut during a conversation going to external numbers. The strange about it is it was cutting in the middle of the call.

When testing, the issue is not showing. so it happens randomly but on the same 2 extensions/users. all the settings seems normal...

Any recommendation on how to troubleshoot these kind of issues?



both are 7940

Rcvr Codec: G711u

Sender Codec: G.711u

Rcvr Size: 20 ms

Sender: 20ms Size

Rcvr Packets: tested for over 3 minutes and both rcv & sent packets increased simultaneously

Sender Packets: as above

Avg Jtr: 0 - this did not change during the call !

Max Jtr: 10

Provide the following:

Which CallManager version?

Is this a cluster?

Was anything changed invoking this behavior?

Is this only occurring between external and internal or also internal to internal?

Is the call drop predictable or pure random?

Could you provide with the call flow information of the dropped call?
