5.8.4 Channel Monitor
Channel Monitor, technically DAHDI Monitor allows you to monitor signal level on analog channel
and record the output to a file. Recorded audio files are by default raw signed linear PCM. You
can play it directly to your speaker to listen to the phone call signaling on the analog channel. Or
alternatively you can use a sound editor to visuallydisplay the audio level at both the Rx (audio
Received by Asterisk) and Tx (audio Transmitted by Asterisk).
Usually Channel Monitor can be used to capture the caller ID signaling of an FXO channel. If you
are experiencing caller ID problems then you can perform channel monitor on the FXO port and
analyze the captured packets. If necessary, you can send this file to ZYCOO support for help.
In the "Monitor on channel" field you should select a channel to be monitored, then specify the
duration to monitor. Then click on "Start" the capture will begin. Now you should make a call in
from this channel (port).
After the capture is completeyou'llsee the capture file listed in the "List of Files" section.
