How do you run DAHDI monitor?
First, make sure to run DAHDI Monitor in a new console or screen.
Start a dahdi_monitor capture for the channel over which the call will be used.
# cd /tmp/
# dahdi_monitor <channel> -v -r rx.wav -t tx.wav
Make sure to replace the first parameter <channel>Â with your channel number.
Place your test calls or wait for the failure to occur. Â
When a call does fail, please note the time of failure and provide any other information available about the failure, such as: Â internal extension involved, external number involved, Asterisk server IP, SIP extension IP, or SIP call-ID. You can get this information by looking at the Asterisk CLI on separate window.Â
Execute "ctrl + c" in the console where you ran the dahdi_monitor capture in order to stop that recording.
Collect your files in the '/tmp/' folder, or wherever you specified them to be placed while completing stepÂ
