[Hai-users] VoIP compatibility

[Dave Horoschak]

Thanks...

Disabling dead line detection fixes the phone line trouble indicator, so 
the system idles in a state of SYSTEM OK.  That's a good start (though 
I'm not sure if it's a great idea to leave it this way permanently.)

I understand the method for the off-hook detect value, except that the 
phone status is always 0 regardless of whether phones are on hook or off 
hook.  The only thing that makes that value change is an incoming call.
