[cisco-voip] PBX supervisor signalling

[Vance Shipley]

Raj,

If your PBX provides answer supervision signaling, a big if,
you will see a momentary reversal of polarity on the line at
the time of answer.  This is trivial to determine, just put
a volt meter across the line and make a call.  When the called
party answers you will either see a brief but very obvious 
fluctuation in the reading seen on the volt meter or you will
see absolutely no change.
