TDA50 Door Phone Redirect 1

[Gstar5327]

Want to redirect a door phone at night to the paging system via a tone generator for door bell service only. What's the "standard", if any, for doing something like this. Doesn't need to be redirected, can just bring the tone generator online at night. Just need a louder "door bell" at night without adding any branch wiring or, more importantly, buttons.Proficient at PT programming. Door phone is already redirected at night to the production phone but it's not loud enough and wouldn't cover the area that the PA system does.
Thx

well there is no problem getting the external paging system to ring for doorphone at night ( make doorphone night destination 600)but how do you talk to the person once they have pushed the call button? you could try a *42 or *43 on intercom when howler comes through ????
