Hello, if you want to see some statistics while ser is running use: 'serctl moni'. But SER is not a call stateful proxy, so you won't see there the list of active calls. To keep trace of the calls you can use acc (accounting) module. Another way is to write some messages into system log using xlog module (xlog function) when the INVITE/ACK/BYE/CANCEL requests pass your server. }Daniel On 9/30/2003 1:02 PM, manu v wrote:
