I’m trying to adjust some of my gains for my zap channels. My card has 8 ports. Two are direct lines to the outside world and the rest go to an old PBX. I removed the txgain and rxgain options from the zapata.conf file. I then edited all the channels in the zapata-auto.conf file to contain their own gain vales. I hope this is safe to do since that file does state “do not hand edit this file.” (I have my file backed up in case I auto generate over top of it accidentally.) This is working and I can now control the gain on each channel separately. My question is how can I set up an incoming rout to generate the “type 102 milliwatt test line” tone via FreePBX? I really don’t want to dig into the extensions.conf file unless I need to.
I also wanted to get some opinions on the usefulness of the ztmonitor app. Some say using it is pointless just go by ear. Others say the graphical bar is useless and to patch it to spit out a numeric value instead. Some say to adjust the gain so the bar graph is at about %50 some say to adjust to %100. Personally I’m just adjusting the gain still I get %100 without clipping above that using a milliwatt test line. This seems to be plenty loud without distorting anything.
All input is greatly appreciated.
Thanks for all the hard work FreePBX!
