[Asterisk-Users] Echo cancel on HFC-S cards and CIDNum setting on outgoing calls

[Christian Gansberger]

hi all!

I'm running an Asterisk-box with bristuff-....RC8n and 2 HFC-S cards.
I m located in Vienna/Austria. I have the problem that on outgoing
calls i hear my voice as a short echo (about half a second).  This
occurs not on every call.

I tried some changes in my zapata.conf, with rxgain and txgain
settings, but to me its
hard to find a configuration which is good for every call i make. Is
there anyone in the list who has an asterisk running with HFC-S card
(in Austria), with the right settings for the echo cancelation (for
Austria Telecom NTBA)?
