Using Sangoma A200 FX0 card and 80% of incoming faxes fail. I don’t quite understand the tool, but I did a zttest and get the following:
@asterisk_miami zaptel]# ./zttest
Opened pseudo zap interface, measuring accuracy...

First, is 99.7% bad? What could be causing this problem? How can I get Asterisk out of the picture and test the lines to see results? And second, am I really measuring my FX0 connection? Because zttest says “Opened pseudo zap interface”.
My users are also experiencing dropped calls over the ZAP channels and occasional noise.
Thanks
