[asterisk-users] Doorphone vs. Grandstream BT101

[marcotasto]

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.

Thank you and bye,

Marco Signorini.
