Hi Erik,<br><br>Asterisk by itself does not have the ability to alter the media stream with regards to volume. Your zap config will allow you to set rxgain and txgain for the Austrian ISDN, but that might not suit your purposes for all other calls that use this trunk.
<br><br>I believe it was mentioned here before that this might be an interesting application for Justin Tunney's VoiceChanger application ( <a href="http://www.lobstertech.com/code/voicechanger/">http://www.lobstertech.com/code/voicechanger/
</a> ). It's a replacement for the dial command that alters the pitch of the media stream in real time. I imagine that with some work, a VolumeChanger application could be written based off of VoiceChanger.<br><br>Cheers,

Hi,<br><br>Is there a possibility to control sound levels (higher / lower) in Asterisk<br>(so the codecs). Somebody asked me to evaluate that but I didn`t found any<br>documentation about. I have the opinion that for these (audio) things the end
<br>user client is the only part where I can tune around.<br><br>Problem is for example a (Austria) ISDN --> Asterisk --> SIP / IP ---><br>(Romania) Asterisk ---> mobile forward. Then the sound level is very low.. i
<br>guess thats normal for this kind of different technologies and forwards but<br>if anybody can tell me something better where i can adjust something....<br><br>Cheers,<br><br>Erik<br>_______________________________________________
