Thanks Ken. Yes I would need the microphone too.
I also thought about your solution too but then I have to hang a phone on
the outside. I would prefer having just a face plate with one button on it.
Those one-button phone costs an arm & an leg > US$400...
I am not sure how delicate the circuitry is behind the redial button (anyone
knows?), but i agree that having a relay should protect it...

Maybe the microphone too :)
The redial button might forget the number after a power cut. If the phone
can be programmed to autodial a number, wire the speaker button instead.
Since the circuit for the button wasn't intended for external use, it
might be sensitive to damage or may not like long runs. Consider mounting
a relay inside the phone and have the outside button control this.
I ended up using an analog handset from the dollar store and an ata
programmed to dial an extension when the phone goes off hook. 3 years so
far on the original $10 phone outside. Keep it sheltered from the rain as
the wet connections may cause it to call you.

Subject: [on-asterisk] cheap door bell ip phone
Hi,
I have been looking for a door bell phone and unable to find a cheap and
cheerful one.
Any suggestion is appreciated. I am thinking of converting a simple $40
ip speaker phone into a door bell phone by externalizing the 2 things on a
face plate to be mounted on the outside wall.
1. the speaker.
2. the redial button.
After all, that's all it is ! right?
Rich.
