The "s" extension is used when there is no known called number.  In 
other words, if you are dialing 2000, the dialplan will always prefer 
the priority list for 2000 instead of going to 's', so that is why 
your current system doesn't work.

I assume that you are ignoring the actual number that people are 
dialing, since you are forcing them to re-enter an extension after 
hearing a recording.  This seems a little odd, but that's what you 
describe, so I'll give you an example with that method.  I use the _. 
modifier to grab "all dialed sequences" and then simply re-map that 
to a new context and extension for ease of processing.  If you're 
dealing with wildcards for "all numbers", you should get rid of them 
as quickly as possible and turn them into something that can be 
handled without using wildcard matching.   I could have easily 
specified a string instead of a number (i.e.: "allnumbers" instead of 
9999) as that eliminates the ability for the normal DTMF user to 
input your "magic" secret number.  However, that is up to the 
programmer as to what method they choose.



[from-sip]
exten => _.,1,Goto(from-sip2,9999,1)

exten => h,1,Hangup


[from-sip2]
exten => 9999,1,Answer
exten => 9999,2,DigitTimeout(3)
exten => 9999,3,ResponseTimeout(10)
exten => 9999,4,Background(dir-intro)

exten => h,1,Hangup
exten => t,1,Goto(9999,4)

exten => i,1,Playback(invalid)
exten => i,2,Goto(9999,4)

exten => 2001,1,Dial(SIP/2000,20)
exten => 2000,1,Dial(SIP/2000,20)
