I have the same problem setup with one of our customers, but I have a
different problem. I have Grandstream ATA 486 connected to clients
doorphone system and clients *. I have two problems: first, when someone
is calling from the doorphone, ATA doesn't recognize the called number
correctly. 2 or tries out of 10, ATA get's the number wrong. I have
tried all kinds of DTMF settings, relax dtmf and so on, nothing helps.
It seems to me, the doorphone's generated DTMF tones are too short. Ok,
that I can resolve with some simple hack, but bigger problem is, when
secretary presses 8 on the phone, to open the door, doorphone doesn't
recognize the tone. Customer has SNOM 190's and BT-100 on their network.
Now however long I press the button on the phone, * still sends a very
short tone on the line. And that doesn't seem to enough for the
doorphone to recognize. Is there any way to make * generate longer DTMF
tones?

Hello,
I have a customer who has their front door integrated to their current
phone system. If someone presses the buzzer, the secretaries phone
will ring, and she can talk to the person at the door. By pressing **
she can release the door.
Anyone have any sort of integration like this. Are there IP devices
anyone is using?
They have a pizza box server as their asterisk server with a T1 card.
No more slots, so if I want to use the existing infrastructure I will
need to build a second server with an FXO port. Kinda stupid having a
second server just to open the door.
Any suggestions?
Cian
