Having a very intermittent issue that is causing some distress. Issue is that when a call comes in to the gateway and is answered, caller will ask to be transferred. IP phone user will hit transfer soft key and then the call will proceed to drop. Like I said this is VERY intermittent. Happened only once today, and i tried to reproduce the issue three times without any luck.
Now for some background on the setup.
Call Manager is 4.1(3)es128
Gateway is an MGCP gateway with FXO ports.
All phones are registered back to the call manager and transferred calls are not across the WAN. They stay in the LAN. Users state that there are no errors or any indication on the display of the phone.
