asterisk users - Oct 2006 - Occasional one-way audio - Sangoma A101

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

Hi Mike,

Sounds like you're having about the same problem Giorgio and I are having.
I'd be really surprised if you don't start having the same problem from
SIP-SIP calls to.  I also have a Sangoma card, and originally thought it was
only on calls coming from a PRI.  But as time has moved forward, the issue
really appears to be between the Polycoms and Asterisk.

The next time it happens, try hitting a digit (like 5) on the polycom and see
if the audio becomes available.

BTW - our other discussion on this is called "random one way audio and
noise
between SIP phoneson same LAN"

Mike,

I'm not able to download the newer polycom software(s) 'cause I'm
not
"certified" in anything.

I just saw the announcement on the Asterisk updates today. I'll get them
installed tonight...
