Calls to the pstn on our x100p experience a very low volume. Any parameters to change this ? Thanks, Chris
Brian West had sent this to the list back in December. Check out google for more info. Here is an exceprt: You need to adjust the rx/tx gain This was just covered like 10 times last month. cd /usr/src/zaptel ./ztmonitor 1 -v (or some other channel) Then in /etc/asterisk/zapata.conf while watching the ztmonitor during a call.. talk normal. You will prob. notice the rx side doesn't jump very far up the scale. Raise the rxgain to about 5 and the txgain down to say -1.5. Restart asterisk. Make a new call. Watch the bars.. they should hit about mid ways on both sides when talking at a normal volume. Also in zapata.conf enable echotraining. I posted about this about 3 days ago.

Change the values where -3.0 is low volume and +3.0 is a higher volume. Understand, however, that changing these values will likely impact the amount of echo you have to put up with to some degree.

Chris, Be careful with setting the volume in this manner. This tip might save you a bunch of headaches. I adjusted the TX on my X100P cards to low negatives values in accordance with the feedback I received from ztmonitor. When I achieved the levels that were satisfactory to me an interesting problem arose. My X100P would not longer dial out. This makes complete sense now, because the TX levels were not high enough to trigger an "off-hook" state. But at the time I was trying to minimize echo and changing a couple of other things. This problem completely baffled the Digium Tech guys and only after going to back to old CVS, different hardware, checking impedance on our lines and a little sitting back and digesting did it the solution present itself. So just a word of warning, if you are messing with these settings and you can no longer dialout, change them back before you check anything else. Sincerely, Ryan R.
