[Asterisk-Users] Invalid extension handling

[Kanuri, Seshu (Company IT)]

Use Gotoif instead of Goto. Check Gotoif usage.

This will give you enough features to fork the calls after the extension
is re-entered

Subject: [Asterisk-Users] Invalid extension handling

When an outside callers hits my system, I play them a welcome message
and ask that they enter an extension.  If the extension is invalid, it
tells them so, and asks them to try again.  The relevant logic for this
is:

[extensions]
exten => _2XXX,Dial(SIP/${EXTEN})
;
exten => i,1,Playback,invalid
exten => i,n,Goto(incoming,_NXXNXXXXXX,1) ;

[incoming]
exten => _NXXNXXXXXX,1,Answer
exten => _NXXNXXXXXX,n,Background(welcome)        ; play welcome msg &
ask for extension
exten => _NXXNXXXXXX,n,WaitExten(5)               ; Wait for extension


This works fine, however, there is one special case that I would like to
handle differently.  If the caller inadvertently presses the # key
following the extension, I would like to discard the # and then send the
call back onto the stack.  I know how to strip the #, but I can't find
another command like WaitExten that will reprocess the call as new.

Any ideas are appreciated.

Thanks,
Adam
