[Freeswitch-users] How to send a tigger and monitoring

Allo! Just Wondering if there is an easy way to do this: a) when we got an outgoing call that meets a regexp to send a tigger, like an email or a nagios push alert b) how to measure a counter for concurrent calls,and total calls per day. I'm in the willling to do a nagios pluging for this but i i dont know how to grab data. Regards, LD
