Voip over frame

[rfullmer]

I am having some qos issues with voip over frame with 4 voice ports using FXS and FXO ports. The main problem I am having is with echo. Can someone please give me a basic idea of how to config this?

I am using traffic shaping and echo cancelling and everything I can think of, am i missing something?

thanks very much!

You can also look at the DB levels. If the FXO/FXS Db level are too high the echo cancel will not help.

thank you , i did use this info..it did help my echo problem, now I am having a voice quality problem.

I am told that the confersations "cut" in and out periodically. I do have some qos settings and have the voice prioritized. It is not a traffic problem either..the data link is only about 15 or 20% utilized. Please help!
