I'm getting complaints from a customer that on every few calls they receive the two parties can just barely hear each other forcing one of them to hang up and call back.
They have a 2651xm with the voice aim terminating a PRI. There has been a lot of echo complaints as well so I have the echo cancel coverage at 32ms.
They're using call manager 3.3 with sr2.
I'm waiting to find out if the problem is consistent with calls from a certain area code or if it only happens on incoming calls.
Not a lot to go on but maybe someone has a suggestion.
