[asterisk-users] RES: RES: RES: RES: How to invoke a binary file from the dial plan?

[Rodrigo Pimenta Carvalho]

Ok Kevin.

Thank you for the information.
Now, I will try to build a prototype to see how everything works. If I have a new doubt, I will post it here.

Best regards.

The way I would probably approach what you want to do is that the button action state would be dependent on if you are in a call or not. If you are in a call, it sends whatever DTMF digits you want to use for this feature. If you are not in a call, it could dial an extension whose purpose is to do the same thing.

I have an outside number that when dialed checks that your caller id number is in an approved list and if it is, sends the gate open signal. This is the same gate open signal that the feature code uses (the call to System()), it is just reached by making a sip call. Nothing says a call has to connect two phones together. You can answer the call inside of Asterisk and do stuff based on what number you called or what digits the caller enters with their keypads. Lot's of opportunity to make the system do exactly what you want.
