We have a weird problem. Every day at 2:00PM the calls get abandoned for about 1 to 2 hours. The calls are still connected, but doesn't get routed to an an agents, I guess. See below the current setup.
Nortel PBX/Key System is connected to PSTN. Nortel then connects to Call Manger 4.1(3) over Q.Sig. Call Manager then connects to IPCC Express.
I was thinking of enabling CCM Trace in Call Manager to see what happens, but also wanted to have a feedback from forum to see if the issue can be resolved.
