[Asterisk-Users] Voice cutoffs

[Anton Krall]

Guys.. I just noticed that my grandstream handytone 286 ata are having
problems with voice cutoffs... We can listen to the person on the zap
channel (x100p cards) without problems but they sometimes listen to us with
cutoffs.. like "He ...lo..... ow...r.. you" and it comes and goes.. this
doesnt happen all the time but often enough.
 
Any ideas what might be happening or what do I need to send you to help me
debug this issue... 
 
Thx Guys!
 
BTW, my ATAs are using ulaw.
