asterisk users - Apr 2006 - audiocodes with asterisk:- newbie

Hello friends,
  I am using SIP on Asterisk 1.2.4. All my configurations are working perfectly
on a Welltech fxo box. But today I changed to an audiocodes MP104 fxo box. All
the sip signalling works fine but the noise is something like an alien invasion,
I mean, its completely outrageous. I dont know what to do. Has anyone got an
audiocodes with asterisk working. Please help me with some configurations in
audiocodes



With warm regards.
