 how to get the Asterisk system to answer and give me dialtone immediately.
 Any ideas or recommendations would be greatly appreciated.

app_disa will give answer and give you dial tone, wait for an authentication code, then dump you into a context where you can make your outgoing calls. Unfortunately, it needs a "#" at the end of the authentication code.

A quick glance at the code suggests that it could be changed to expect a
fixed 7 digit access code.

It would be easy enough just to cut the first seven digits off the number and run it through a comparison pass, and not use the authentication routines at all.

exten => h,1,Hangup
exten => i,1,Congestion

exten => t,1,Congestion
exten => t,2,Hangup
;
;
[main2]
;
; Now, set the AUTHCODE to be the first seven digits of EXTEN
;
exten => _XXXXXXX1XXXXXXXXXX,1,SetVar(AUTHCODE=${EXTEN:0:7})
;
; ...and then forward this call out to a new context and extension,
;  where the new extension is the 7th through 17th digit of the old EXTEN,
;  which should translate into 1-123-456-7890 or whatever it was that

;
exten => _XXXXXXX1XXXXXXXXXX,2,Goto(main-dial-routine,${EXTEN:7:17},1)
;
exten => h,1,Hangup
exten => i,1,Congestion
exten => i,2,Hangup
exten => t,1,Congestion
exten => t,2,Hangup
;
; end of example


This would end up (if the user entered the appropriate 7 digits and 1-npa-xxx-yyyy phone number) with passing the authentication code to the main-dial-routine contained in ${AUTHCODE} and the ${EXTEN} set to the number dialed.


You could also use the "Cut" application to perform a similar purpose to my example using substring identifiers, if you wanted to put a pound or star (or for those telephonically exotic among you, the A/B/C/D) key separator in between the passcode digits and the phone number.
