asterisk users - Jan 2007 - ztmonitor output while idle

Hi All,

I am trying to tune out some echo on a analogue line and have run 
ztmonitor to get some info. When i run it, i get a RX reading when the 
line is idle - is this normal? eg:

[root@004063E4ECBC zaptel-1.2.10]# ./ztmonitor 1 -vv

Visual Audio Levels.
--------------------
  Use zapata.conf file to adjust the gains if needed.

( # = Audio Level  * = Max Audio Hit )
<----------------(RX)----------------> 
<----------------(TX)---------------->
 
         Rx:   132 (  132) Tx:     0 (    0)

This happens on all 4 lines with varying rx levels

Cheers,

Ben

When the line is on-hook, its sample values are basically meaningless, I
gather.
