More fun with Door Phones.

Jeff,

This took a little tinkering, but I fixed something else that was wrong with mine in the process. I do not know how to open the door, but I can make it auto answer when someone pushes the button.

Set up the FXS extension in FreePBX and change immediate to yes. Put this extension in a different context. Here is my test context.

[from-junk]
exten => s,1,answer()
exten => s,n,playback(touchtone1)
exten => s,n,hangup()

As soon as you pick up the phone, it starts playing the touchtone1 file. Don't laugh at my context name :)

Happy Channukah

Would anyone know if i can connect a greandstream ATA, and set the "Dial this telephone number when off hook" option to the ring group, and let us push "5" if we want to open the door?

As well, if nobody answers, or after we hang up the phone- will the person outside hear the busy signal? This is my main concern- about whether or not the Panasonic would hang up the call.

Thank you very much

Oh. What I'm just planning on doing is just cutting off the pots lines from the panasonic box and plugging the grandstream's analog port into an existing phone jack. Then on the grandstream just set the option to dial a # when off hook.

I'm just worried about hanging up, or no answer.

I'm doing a very similar thing in my job right now. We've got an old Panasonic KX-T61610 whose only function now is to run the door phone. (Everything else is using our Trixbox.)

The door phone is set to ring extension 11 on the Panasonic KSU (I don't know if that's the default or not, but that's how ours is programmed). I put one end of a one-pair telephone cord into the KSU's extension 11, and the other into the Trixbox's FXO port (on a TDM card).

In Trixbox, I've got an incoming route set for that specific Zaptel channel that goes into a ring group of my office phones. (The ring group has an announcement at the beginning, which I find helps to start the audio on the door phone.) If no one answers the call, it's terminated (with an appropriate announcement, of course).

If I could have found a SIP doorphone for a reasonable price, I would have ditched the entire Panasonic system entirely. But, since we already had the hardware, it was a simple process.
