[Asterisk-Users] X100P check for Dialtone

[Jared Davies]

Is there any way to make the X100P to check for a dialtone before 
dialing?   My roommate is tired of hearing random dialing in his ear 
when he's on the phone (same circuit as the X100P).

I know one solution is to just put in a TDM400P for the house, but I'd 
rather get away w/o having to do that.

Thanks,
Jared
