[asterisk-users] Setting a threshold for asterisk to take ZAP line off hook ?

[Mojo with Horan & Company, LLC]

I think when a PSTN line says 'Ring' it's simply for aesthetics... The 
line is 'answered' the instant * connects to it for two-way audio... 
(well not that instant but somewhere in the connection process.  When 
you are hearing ringing from the PSTN through a zap card, the rings are 
coming from the phone company and are just sound.  * doesn't decode that 
and act on it yet.)
