[Asterisk-Users] Re: Random Echo

Interesting, how do you configure T1 Tellabs 2572's? We also have same issue
and I am tried resolving this echo issue. I did some google search but
didn't find any details, about how to configure between Adtran 750 and
T100P. If you have already done, please give us some details.

Regards,
KD

Yup inline T1 hardware echo cans :)
I am using some older 64ms T1 tellabs 2572's, stops echo in its tracks
