Hello,
I have a PRI coming into a Digium TE122B with hardware echo cancel,
but we are still experiencing echo on the first 10 seconds of a call.
Is there anything that can be done about this?

I have tried contacting digium support, but have not heard back from
them (placed a support incident about a week ago).

I see on digiums website that some of their card have a VPMOCT128
Octasic echo cancel, but the TE122B comes with digiums VPMADT032 echo
canceler.

Is the octastic echo cancel better? Should I look into a card with
Octastic echo canceler? I see Sangoma has a single port with T1 with
Octastic echo canceler or would have to move up to the dual span card
to get the Octastic echo cancel on the digium card.

Joe,

I'm unable to find an incident in your name in Digium Support's tracking systems. Can you email me off-list with a case or reference number, or give me contact information so one of our technicians can work with you to address your echo issue?

A week-long wait is not typical of Digium Support. We strive to be as responsive as possible, and typically do much better than that. I'd like to understand what happened here, so we can make sure that we consistently provide quick and reliable support.

Thanks,
~Kenny Shumard
Digium Technical Support Manager
