Let's suppose you have a PSTN line with multiple extensions. One of these extensions is connected to an Asterisk FXO port. For reasons that I won't go into, the "normal" configuration of the system is that when a call comes in on the PSTN line, Asterisk *does not answer* -- the other extensions do whatever they would do if there were no Asterisk system there.
When I hear one of these extensions ringing, I want to be able to dial an extension on the Asterisk phone system that will allow the Asterisk FXO port to answer, and from there on Asterisk takes the call.
Any thoughts on how to do this?
-Thanks, Jim
The answer to your description is "No, I don't know how to do that." It may be possible, since the chipset on an X100P or other Tigerjet chip _might_ be able to look at line voltage without actually seizing the line, at which point it might be possible to detect a pickup event somewhere else on the loop, which in turn then might be able to activate a "silent pickup" which could listen for DTMF.
However, I doubt that is feasible unless you really want to dig into the Zap drivers and/or the code logic on the Tigerjet chips.
A more reasonable way to do it would be to buy a TDM4xx card from Digium, and put one FXO and one FXS interface daughtercard(s) on it. Run the line from the phone company into the FXO line. Create a dialplan that pushes any inbound call on the FXO directly out to the FXS. I am guessing (though I don't know for sure) that it will not pick up the FXO until the FXS is answered. At that point, you can manipulate the dialplan with the # button (yuck - see my previous rants on why Dial needs to be extended to do more stuff with single-digit keypresses, but that's another story.)
