[Asterisk-Users] "Mic-To-Speaker-loop" on ZAP lines???

[Maik Hassel]

Hello everybody,


my setup consists of an asterisk server with a TDM400P and a couple of  
softphones (SJphones) ... everything works well (thanks for all the help 
by the way),(echotest, voicemail, sip to sip) works fine and in good 
quality.

Now, only when I dial out to an analog line, even when I just "pick up" 
(dial "9"), I hear my own voice in the headset, which is really quite 
annoying. This only happens when I dial out of a ZAP channel, never 
else, so i suppose it's a configuration thing?

Does anybody have an idea what I can do to prevent that?

My zapata.conf is below, THANKS a lot for any help

Maik
