Sangoma echospike tools? Please elaborate!
See sangoma's -users posting from Dec 13th, which I quote:
"I just wanted to let you know that we do provide a tool to debug echo.
We send a unit impulse and record the Finite Impulse Response (FIR) so it
can be plotted and analyzed. The code that does this is the release at
ftp.sangoma.com/linux/custom/2.3.4. Instructions on using it are in the wiki
in http://sangoma.editme.com/wanpipe-linux-asterisk-debugging.
Although the code is wanpipe, all the interaction is at the zaptel level, so
I am pretty sure it will work on Digium or other cards as well.
Just being able to see what the echo looks like on a troublesome line gives
quite a lot of info. You can see if the echo is delayed, or markedly
non-linear."
I haven't tried it as yet but plan to do so.
Correct, this is what we used.
Florian
