[Asterisk-Users] IAXy audio troubles (only on INCOMING calls)

[niels at wxn.nl]

Hello All!

I just got my IAXy.. Configured it.. Got it Up and Running 

Calls OUT have no problems (that means from IAXy -> Asterisk ->
ZAP/SIPclient/IAXclient) 

Calls IN do have problems (that means from ZAP/SIPclient/IAXclient ->
Asterisk -> IAXy) 

On those incoming calls on my IAXy I hear the other party on my IAXy,
But this other party can't hear me (the audio that's beeing sent from
the IAXy to asterisk can't be heard)

Does anyone have any idea what I can do about this?

Is this a common problem?
