[asterisk-users] Toll free pattern matching

[D'Arcy J.M. Cain]

I have this in my config:

exten => _800XXXXXXX,1,Verbose(0,${CHANNEL(peername)} Calling ${EXTEN})
  same => n,Dial(SIP/tollfree/1${EXTEN})
exten => _1800XXXXXXX,1,Verbose(0,${CHANNEL(peername)} Calling ${EXTEN})
  same => n,Dial(SIP/tollfree/${EXTEN}) 
exten => _NXXNXXXXXX,1,Verbose(0,${CHANNEL(peername)} Calling ${EXTEN})
  same => n,Dial(SIP/trunk/1${EXTEN})
exten => _1NXXNXXXXXX,1,Verbose(0,${CHANNEL(peername)} Calling ${EXTEN})
  same => n,Dial(SIP/trunk/${EXTEN}) 

I came across
http://stackoverflow.com/questions/7235291/asterisk-priorities-that-have-a-possibility-of-matching
which seems to imply that the above won't work and that all the calls
would go to the trunk.  However, this is working as expected for me.
Did the behaviour change in the last four years or could I run into
problems with this setup?  Perhaps I am misunderstanding the poster's
issue.
