The tool you're looking for is /usr/src/zaptel/ztmonitor [EMAIL PROTECTED] zaptel]# ./ztmonitor Usage: ztmonitor <channel num> [-v] [-f FILE] [EMAIL PROTECTED] zaptel]# ./ztmonitor 1 -v Visual Audio Levels. -------------------- Use zapata.conf file to adjust the gains if needed. ( # = Audio Level * = Max Audio Hit ) <----------------(RX)----------------> <----------------(TX)----------------> ##################* Keep in mind that tool is nothing more then an audio VU meter and was not intended to be an accurate means of measuring transmission levels. I think bkw (probably with Mark) wrote it back in the November/December timeframe as a simple tool for adjusting rxgain, etc. About that same time, the echo cancelling mechanism (for the x100p) was rewritten to "sense" the audio reflection (or echo) during the first half-second or so of an initial pstn call. (That was a substantial improvement over previous cancellation methods without a doubt. If I recall recorrectly, that mechanism was reduced to sending an outbound short duration pulse or burst, and measuring the reflected energy. Sort of a snapshot at the start of an analog call. It's okay, but certainly not the equivalent of commercial analog cancellation products including mux's.) I've not had to revisit the x100p gain adjustment effort for several months, but seems to me that it was necessary to completely stop and start * each time an adjustment was made to the rxgain/txgain settings in zapata.conf (a simple reload wasn't adequate).
