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?
