Modifing and/or adding tones used

I know phreaking is dead, but is it possible to add 2600hz, KP and ST as buttons/funtions on asterisk?

if a user calls and sounds 2600, he will be taken to another AutoAttendant where the user can enter KP NPA NXX XXXX ST and get an outside line or SIP to connect him to that number?

im not sure if this is the right or wrong place to ask, if so, im sorry. im new here.

I do have knowledge in linux so this wont be a problem setting up.

Thank you.
