[Asterisk-Users] Problems with IAX configuration

[Reto Stauss]

We have a running Asterisk on a small server (RH 9.0) und were able to make calls via SIP.
Since the quality was rather poor (one of us has only a 150/75 kbps DSL connection, iLBC
did not work(?)) we tried to setup clients (FireFly) and Asterisk for connections via
IAX.

In some point seems to be a mistake. Asterisk says:

externsions.conf looks like this:

[from-iax] 

exten => 83022266,1,Dial(IAX2/83022266 at mpolpbx.dynalias.org) 
exten => 83022266,3,Hangup 

exten => 83022777,1,Dial(IAX2/83022777 at mpolpbx.dynalias.org) 
exten => 83022777,3,Hangup

I guess the problem lies in extensions.conf but was not able to figure out the correct
seeting.

Any hints?

Thanks
