[SR-Users] SIP Trunk Usage Monitoring

Hi All, I recently interconnected to an upstream carrier using Kamailio 3.0, working fine. We have configure 2 SIP trunks for failover/redundnacy. I'm using dispatcher module to round robin calls to the carrier. I wanted to monitor trunk usage between us. I was reading in the devel 3.2 about some native monitoring in the new dispatcher module without the need to load the dialog module. Can I use the new module in version 3.0 or will I need to upgrade the core to 3.2? I typically will not use dev software in production, so can anyone suggest a light method of trunk usage monitoring for ver 3.0? I'm not opposed to using the dialog module, I'm just not familiar with it and not sure the best way to integrate it for usage tracking. I don't need to do billing or capture cdr's on the SIP-Routers so the simpler the better. Any guidance will be much appreciated. Thanks. JR -- JR Richardson Engineering for the Masses
