Hi, i have some problems in the calls between a Norstar and a Nortel option 11, both are connected to a 2811 via E1 with the IOS is c2800nm-spservicesk9-mz.124-15.T3.bin both routers are using h323. We also have a Callmanager 22.214.171.12400-2 that interact with both PBX.
The problem is that when i make a call from the Norstar to the Nortell or CCM the call listens choppy and sometime the voice goes only one side.
Do you know of some debug that i can apply to see ISDN errors, h323 errors, or QoS errors.
Thanks in advanced
