[asterisk-users] interactive menu with DTMF tones

[John Von Essen]

Before I attempt to program a system like this, I wanted to see if: A) 
its possible, and B) its too insanely difficult for a perl developer.

My office building has a dialer on the front door so people can call me 
and gain access. The dialer on the door has a full keypad, and 
basically just rings through to me, when I answer I can talk to the 
person, they talk back, and if I want to let them in I hit 9 on my 
phone - and the system unlocks the door.


Here's my dilemma, sometimes people need to get in when I'm not around. 
The dialer can follow me, and go to my cell phone - but I dont always 
answer that.

So I am wondering if its possible to build an interactive prompt/menu 
system so when the dialer rings the number, the interactive system 
runs, user must enter an account number, then pass code, and the system 
verifies, if everything checks out, the system will then send the 9 
tone back through, and the door will open.

Does this sound like something doable? I am very proficient Perl 
developer, but need a push in the right direction.

Thanks
