[asterisk-users] Strange dialplan matching issue

[OCG Technical Support]

We use extensions like "plant201" and "tunnel12" so it does work in 1.4

On extensions.conf.sample I see this:

; Extension names may be numbers, letters, or combinations
; thereof. If an extension name is prefixed by a '_'
; character, it is interpreted as a pattern rather than a
; literal.  In patterns, some characters have special meanings:
;
;   X - any digit from 0-9
;   Z - any digit from 1-9
;   N - any digit from 2-9
;   [1235-9] - any digit in the brackets (in this example, 1,2,3,5,6,7,8,9)
;   . - wildcard, matches anything remaining (e.g. _9011. matches
;       anything starting with 9011 excluding 9011 itself)
;   ! - wildcard, causes the matching process to complete as soon as
;       it can unambiguously determine that no other matches are possible

Maybe after using '_' Asterisk is waiting for one of the above pattern 
matching characters.

a. The 'hilton-' part of your dialplan might not being considered valid, 
and Asterisk *might* be trying to match the 'XX' part LITERALLY, and 
would be trying to reach extension '2XX'

exten => _hilton-2XX,1,Goto(hilton,${EXTEN:7},1)


b. then, in:
exten => hilton-203,1,Goto(hilton,${EXTEN:7},1)

You provided the real extension number (after you take out the fist 7 
digits).

So, Asterisk reaches '203', etc.



Try only using valid pattern matching characters in your dialplan to see 
if it works.
