In a very simple voip environment, the central is 3640 with NM-HDV module, the remote offices use 2600 with FXS. We want to monitor the call histories. I searched in CCO, but didn't find a easy and completed solution for a small-scale voip environment. I found some information in CCO, know something about command like 'gw-accounting voip' , and a feature of ACS 2.6--Radius Voip Accounting.
But still don't have a very clear idea about that, can someone give advice? Is it easy to config without additional hardware or software.( mabye just a syslog server or Radius server)
