We have just recently had a few complaints from one of our sites regarding some of their calls.
Apparently the users can hear the caller, but the caller cannot hear them. This happens in the middle of a call.
We're running CallManager 4.1(3) and all calls at this site are going through a single PRI.
I have no idea where to even begin looking into this issue or where to find any logs or event information for a bad call. Any help would be appreciated.
