[asterisk-users] Occasional one-way audio - Sangoma A101

[Mike Clark]

We are having an occasional one w-way audio problem that occurs about 
every 25 - 30 calls on a system configured as follows:

Asterisk 1.2.12.1
Sangoma A101 w/wanpipe beta9
Polycom 500s w 1.5.3

This happens only on inbound calls from the PRI. The external caller can 
hear our customer answer and say hello, however, our customer cannot 
here their caller. Typically, the caller calls right back and all is 
fine. There is no discernable pattern as I can tell. Anyone have, and 
hopefully fix, a similar issue?

Thanks,

Mike Clark
