[Asterisk-Users] Low volume/ audio problems on TDM400 card

[news.asterisk.users]

That is the first thing I did.. rxgain seems to help to make it louder 
when the two PSTN lines are bridged but also affects
the audio quality adversely.  It's very touchy.. it also causes horrible 
feedback (loud screeching when lines bridge). 
I've upgraded zapata and libpri too.
