May not be the most elegant, but I have simple mysql commands that run every 5 minutes and dumps those details (and other details) into MRTG.
I also use that same output to track certain calls (lengths, etc) for other reports.

Quick and it works for my setup ...

HTH,

Greetings,
I have a challenge which I can't imagine is unique to my situation.  I have agreements with multiple ITSP/SIP providers for inbound and outbound use cases.  I am trying to figure out a way to track and monitor - on a per trunk basis - statistics about open dialogs.  In the end, I would like to have nice graphs that show my usage throughout the day... and most importantly, my max open dialogs so I can determine if I am coming close to my max sessions with any particular carrier.

Does anyone know of a tool which could help me track this?  It looks like Kamailio has some SNMP modules, perhaps SNMP + Cacti might be the common solution?

Any input is greatly appreciated.

Thanks.
