Hi,

I have an Ubuntu box running FS1.0.4 which has been processing a good
volume of calls between local users with soft phones (Xlite) and GSM
handsets via a number or Portech gateways, this has worked very well
for some time and audio quality is very good.

I've now added a Sangoma A200 with 4 ports hooked up to 4 PSTN lines,
configured openzap and I can originate and answer calls on the the
openzap lines fine, however these calls via opezap all seem to suffer
from significant noise, the audio path works fine in both directions
but noise seems particularly bad at the local soft phone end. Quality
of all other calls through the box is fine though, any ideas
appreciated ?,

NB A regular handset plugged directly into the PSTN lines has no problems though

Thanks

Steve
