Yes, it seems to be happening on any call that passes over the T1 card. SIP-to-SIP works fine.

(My customer has a lot of traffic on the lines and only sometimes hears this problem). It seemed to happen especially with loud woman voices, but i was unable to reproduce it on command. I have several other te410p's on different locations (with different carriers), without those complaints. Does this also happen on pri to pri calls for you ? Maybe its a combination of carrier volume with the te410p ?
