While troubleshooting Asterisk phone system I figured that I needed a way to see how to show Asterisk calls in progress.

There is a command call “watch” that you can use on the Linux operating system that will show you the active number of calls. There are three watch commands that I am showing here:
Watch the number of active channels #watch “asterisk -vvvvvrx ‘show channels’ | grep channels”
Watch number of active calls
#watch “asterisk -vvvvvrx ‘show channels’ | grep calls”
watch number of active channels
#watch “asterisk -vvvvvrx ‘show channels verbose'”
