[asterisk-users] GXV3000 & Speakphone

[Davis Sylvester III]

I have about 4 GrandStream GXV 3000 video phones.  I have been trying to 
integrate them into our asterisk environment.  All works fine until 
someone trys to use the speakphone function or the conference call 
function (conferencing to inbound call together).  As soon as they try 
either function previously listed the sound quality goes to garbage.  We 
are using gsm as the codec.

I have not tried to use the video support as we are stilling on asterisk 
1.2.

Has anyone experienced this problem?
