I have run into an issue and was wondering if anyone else has run into it or heard of it before. The issue is that every once in a while a call is placed on hold and when the agents takes the call off hold, there is a delay of anywhere between 20-30 seconds (sometimes longer) before the agent and customer can talk again. According to the reports I have gotten, from the customer point of view, the on MoH music stops like the call has been taken off of hold but they hear silence for 20-30 seconds then they hear the agent. From the agent point of view, they just come back to their phone and take the call off hold and there is silence for a bit then they can hear the customer again. Has anyone ever run into this before or does anyone have any ideas as to what may be causing it? We are running 7940 IP phones, CallManager 4.1 and IPCC Express. Thank you.
