[Asterisk-Users] Call quality degradation after time

[Adam Dobrin]

I'm using Polycom 501's; with stable1.0.8, g729 and a very decent 
machine; we have a PRI interface to a T1. 

Many users complain that after a given amount of time, say, 30 or 40 
minutes on a call, the outside party complains that their sound keeps 
'cutting in and out'.  I believe that the incoming sound quality remains 
fine.

I had read that there may be some soft of memory issue with the 
Polycom's... what else could be causing this?  Will auto-rebooting the 
phones once every few days fix this problem?

Thanks.
