Hello All,

I'd like to gather statistics about call failures. FS already does this for gateways:

freeswitch@internal> sofia status external
    Profile::Gateway-Name                               Data            State  Ping Time        IB Calls(F/T)   OB Calls(F/T)
=================================================================================================
             NAME::NAME          sip:FreeSWITCH@IP_ADDRESS        NOREG    0.00   0/0     290/453
=================================================================================================
1 gateway: Inbound(Failed/Total): 0/0,Outbound(Failed/Total):290/453

However, this statistic is already aggregated and I'd like it in time series. 

Is there a way to reset it to zero after a lookup in order to figure out how many calls have happened since the last query?
