there are also some commercial door box products available that will
allow voice communication with the door box.
Some may even allow an electric lock to be triggered through a DTMF tone
pair.
All will require an ATA, but not much in the way of construction experience.
Google will find some
Viking and Mike Sandman both have different products.
Some require an FXS, some an FXO ATA
Some even incorporate a camera

Dear Lonnie,
With this project it is not possible to communicate with the person
that is actually pressing the doorbell is that correct?
Correct, only an "off-hook" signal is sent to the ATA. No voice.
I am planning to build this and going to order the needed stuff ...
Thanks for the solution ...
Is this your first soldering iron, electronics project? If so, I'd
advise finding a friend that has some experience to help.
I have a few more questions tough ...
Is my understanding correct that hight-level concept of this is:
- A persion presses the doorbell
- The doorbell will dial via the ATA towards the Asterisk server
- The Asterisk server is doing a action e.g. send SMS, create
voicemail, transfer call to your mobile etc. etc.
Is this correct?
The documentation shows how an asterisk extension is dialed via the
ATA's 'hotline' feature. The extension number (your choice) is
defined in your ATA configuration and your extensions.conf...
; Doorbell Ring Example
exten => 1179,1,Answer
exten => 1179,n,SIPAddHeader(Alert-Info: Doorbell)
exten => 1179,n,DIAL(${DOORBELLPHONES},8)
exten => 1179,n,Hangup
This will occur for a few seconds (4 to 8).
Before you begin any construction, create the extensions.conf entry
and your intended dialplan function, then test by dialing that
extension for 4-8 seconds and then hangup.
When that works as you expect, configure the ATA, and test by
connecting an old POTS phone to the ATA, lift the handset for 4-8
seconds and hangup.
Lastly, when the tests work as you expect, you can proceed to the
electronics portion.
Lonnie
Thanks,

Dear,
I was looking for a not too expensive solution to make my doorbell
asterisk compatible.
This means that the actions are as follows:
- Someone presses the doorbell
- The doorbell is dialing towards the Asterisk server
- The Asterisk server will execute a action based on the dialplan
(send SMS, create voicemail, transfer call to your mobile)
Now after doing some googeling I found this tread:
http://www.mail-archive.com/astlinux-users@lists.sourceforge.net/msg00794.html
I am wondering if anyone builded and tested this exept for Lonnie?
And is this also possible to do with a direct RJ-45 connector and
not having to go trough an ATA?
No, an ATA is required.
Status Report: The project is working well for me, without any further
tweaking, more than a year later.
Thanks for the help so far ...
