[asterisk-users] White noise from TDM2400

[Stephen Kratzer]

Hello. We recently replaced a channel bank in favor of a TDM2400E. After doing 
so, users began complaining that they could barely hear the remote parties. 
We increased gain appropriately for each channel which increased the volume 
of the voices but has also increased the volume of any line noise. It sounds 
like white noise which goes away when either party talks and returns during 
silence. Is there any remedy to this? Thanks.
