I've done all the googling I can on this, and have come to the conclusion that a Grandstream BT101 can be abused to be a door phone. Could someone with access to one, confirm that the following is possible? Researched: 1. When set to auto-answer, dialing the phone will result in a short beep and instant speaker-phone connection. 2. When pressing the "message" button while on-hook, the phone will activate speaker-phone and dial the number configured for voice mail retrieval. Assumptions: 3. Pressing the "message" button additional times will simply be ignored by the phone. 4. Hanging up the other end of the call will deactivate the speaker phone and cause the phone to go on-hook. (This is the behavior I see on a Polycom 430). If the researched functions and my assumptions are correct, this phone would make an ideal door-phone; The message button becomes the call-button, which rings every phone in the house until answered (for intercom). It could even take messages. Listen-in on the door works through the auto-answer feature. Could someone confirm this for me? Thanks!

When the BT is set to auto-answer through the config you get a short warble-like sound and the phone goes into speaker mode (I'm using one for paging in that exact fasion). I'm pretty sure that if you are on-hook, pressing the message button will instantly place the call and go into speaker mode (if noone verifies this I'll try it this weekend). I don't know about #3. #4 is correct when the phone is set to auto-answer. If it is not on auto-answer the phone will play a busy signal when the other party hangs up which I always thought was kind of dumb. -Dave

Something to consider, the BT101's speak phone has no Echo cancellation whatsoever and sounds just awful in a two way conversation. Doug
I did something similar one year ago for a friend of mine that was interested to answer to bell door from internal phones. I used an HT286 with a sort of homebuilt analog hybrid with a microcontroller able to automatically answer when the ring was present on the HT286 FXS line (when calling from internal to the external box) and using the auto-call feature of the HT286 when people press the external button. To terminate the call I used a sort of DTMF sequence sent by Asterisk dead-agi script that the micro detects just to hang-up. I've added on the same box an axis camera to have a sort of video on the LAN. To be able to safely open the door, I made a little box ethernet based able to receive some UDP packets sent by Asterisk through agi when the received call was transferred on a predefined internal extension. It's working well! In my spare time, I'm working to have this solution well packed in an easy to build electronic kit (my friend is using a prototype version). If you are interested, I can post my results and the link to my site when they will be ready.

I used to have a webstore and also deployed many GS BT101s so I have moved and supported several hundred. Nothing but trouble. I do not deploy "toy" phones anymore. The % of DOAs and all of the issues that the BT101s had plus how flimsy it is turned me off. It is not much more for a Polycom 301 which I consider a true business class phone. Set it and forget it. Thanks Steve

If you just took the cradle out of the picture and rigged up a little hook for the wall mount. Maybe this would work, but I am sure you can find something sleek like this for ~$10. Certainly not weather proof but more so than a BT101. http://cgi.ebay.com/ELVOX-Handset-Security-Door-Entry-Phone-8872_W0QQitemZ150098450949QQcategoryZ48636QQrdZ1QQcmdZViewItem Thanks, Steve Totaro www.asteriskhelpdesk.com KB3OPB

Shoot, went there again.No> > I'm not bitter.OK.... Anyways... You could still use a Grandstream ATA and just have your doorbell switch actually be the hook switch for the line, use the h extension to continue ringing phones, send an SMS, jabber message or whatever. Just set the auto dial in the ATA. Or you could just use a regular old doorbell or one of the wireless units sold at Radio Shack, Sears, Wal-Mart, and everywhere. It pains me to say it, but not everything needs to integrate with Asterisk. Sometimes a doorbell should just be a doorbell, why make things more complicated than they need to be?
