Alertdialer needs the caller id as a security feature!
Without it anyone can dial up and activate your system or disable it which could be disastrous!
If your running XP or later you don't need the speech SDK (unless you want the extra Microsoft voices)
AlertDialer uses the Voice to tell you the command was received and action implemented but you can configure it to use a wav file.
If you have the AHP and the myHouse plug-in that will connect you mind you have to make 2 calls before it connects, first to let the system count rings Hang up on the correct ring number then dial back!
Not the best system ! With my cell phone I some times don't hear the first ring so my count would be off!
Also there is no guarantee someone else won't connect between your first and second call thought the chances of that are slim.
I think there are other Phone programs out there that work similar to AHP Doing a Google search may turn up some!
It really depends on the price you put on security
I originaly thought of connecting without Caller Id but I didn't need emails stating "Alertdialer cause my house to be robbed"
