Logging active calls

[vanagon2tdi]

I want to be able to log the amount of active calls at one time. This will tell me if our client is overloading the system with too many calls. How do i enable that on the router, then send it to my syslog server?

show call active voice, can show the active calls or use a cdr in callmanager with

call accounting-template voice

I am thinking of two ways:

1. configure a Radius server and then configure Cisco to send authentication / accounting data to it.

2. Write a Perl script using Net::Telnet::Cisco that will login on every minute (via crontab) to the Cisco, will issue the "show call active voice" command, parse the output and show it to you.
