[asterisk-users] Counting calls in progress from AMI

[Salman Zafar]

Considering this your real question "I want to track the number of calls up
at any given time, through the AMI" ....

Comparable Command Exists !!

You can simply run CLI commands *through *AMI and receive the response.
Command used for this is itself "Command" in AMI. If you still want to do
it by counting the event stream then POE is the best solution if you know
PERL, but still why wasting resources in counting events.If you have other
plans like billing then it is understandable otherwise go easy way and add
a cron job or have a UI in php or whatever.

Manager Command:

Command          command,all      Execute Asterisk CLI Command
