Greetings,<br>I have a challenge which I can&#39;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.<br>
<br>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?<br><br>Any input is greatly appreciated.<br><br>Thanks.<br>
