I want to make a doorbell - Partner ACS R5

[flybob]

I want a doorbell button outside the building to sound a chime at all or certain extensions. I can't work out in my mind exactly how, but I'm envisioning using alert extension settings (for the button, and for chiming stations), part of an old tip/ring phone or something (to access the extension port with my signal), and a sound source with some kind of timer. I know I could buy the doorphone for $250, but I don't think that plays a ding-ding chime and I'm too cheap to buy it (see my Contact Closure hack thread where I'm too cheap to buy even that!).

I'm hoping there's an inexpensive door chime or paging chime unit out there that I could somehow use with the Partner.
Thanks for your help. Hope this is an interesting one.

Well, you don't have to buy a door phone to have a phone at the door! Any type of telephone, even a single line, connected to a station port and programmed as a door phone will function. When the handset is lifted, all phones programmed to receive the door phone alert will "ding-dong" on the intercom, just like a real doorbell. If the door phone is administered as doorphone-2, it is a different tone (back door vs. front door)

Oh, okay! Thanks! Now I'm annoyed with myself for not trying that first, to see what tone alerted at the alert stations. (Of course, complete documentation would have saved all this hassle and more...)
