[App_rpt] app_rpt phone patch

[Bob Peret]

Eric,

I think this is how it works:  If extensions.conf has an entry 
specifying the "D" mode, then the phone patch connection is always "key 
down".  This would be used for a full duplex repeater.  If the entry 
puts the phone in "P" mode then the phone user has to issue a control 
op-6 to enable the PTT of "key down".  Below are some snippets from 
these files.  Hope this helps.
