Calls get disconnected when on hold or during transfer
We have a Call Manager 3.1(3a) with an H323 IOS gateway (2610 router with NM-HDV-E1 voice PRI card). We have a pilot number which is answered by an attendant. The attendant complains sometimes that when she tries to transfer a call or when a call is on hold, the line disconnects. This happens with incoming calls from the PSTN. I suspect that the problem is on the H323 gateway because before we had an old Skinny DE30+ PRI card which worked great with no problems like that.

If you do beleive it is a codec problem do a voice class codec and add g.711 and g.729r8. That should rule out any codec issues. Also make sure if you have a cluster that your dial-peers session targets match up with the callmanager group you have configure for the device pool of the gateway.
