Summary:                    All extensions are patterns (despite it does not
begin with _ (underscore) if extenpatternmatchnew=yes
Description: 
Hi all

In a standart dialplan if you put extension not begining with _, any
uppercase N,Z or X is matching digits, instead the letter itself if you set
extenpatternmatchnew=yes

You can see the full stuff on the forum:

anway here is the essential:

dialplan:

[strange-context]
exten => CHANUNAVAIL,1,HangUp()
exten => CONGESTION,1,HangUp()
exten => NOANSWER,1,HangUp()
exten => BUSY,1,HangUp()
exten => ANSWER,1,HangUp()
exten => CANCEL,1,HangUp()
exten => DONTCALL,1,HangUp()
exten => TORTURE,1,HangUp()
exten => INVALIDARGS,1,HangUp()
exten => sANSWE,1,HangUp()
exten => answer,1,HangUp()
exten => A,1,HangUp()
exten => AP,1,HangUp()
exten => AAN,1,HangUp()
exten => AS,1,HangUp()
exten => AAAS,1,HangUp()
exten => AAAS,1,HangUp()
exten => ZEBRA,1,HangUp()
exten => EXIT,1,HangUp()


correctly read by pbx_config

*CLI> dialplan show strange-context
[ Context 'strange-context' created by 'pbx_config' ]
'A' => 1. HangUp() [pbx_config]
'AAAS' => 1. HangUp() [pbx_config]

'ANSWER' => 1. HangUp() [pbx_config]

'i' => 1. Hangup() [pbx_config]
'sANSWE' => 1. HangUp() [pbx_config]

-= 19 extensions (19 priorities) in 1 context. =-




tests:
*CLI> console dial AAAS at strange-context
*CLI> -- Executing [AAAS at strange-context:1] Hangup("Console/default", "")
in new stack

*CLI> console dial AAN at strange-context
No such extension 'AAN' in context 'strange-context'

*CLI> console dial AA3 at strange-context
*CLI> -- Executing [AA3 at strange-context:1] Hangup("Console/default", "")
in new stack

*CLI> console dial ZEBRA at strange-context
No such extension 'ZEBRA' in context 'strange-context'

*CLI> console dial 8EBRA at strange-context
*CLI> -- Executing [8EBRA at strange-context:1] Hangup("Console/default", "")
in new stack

*CLI> console dial DONTCALL at strange-context
No such extension 'DONTCALL' in context 'strange-context'

*CLI> console dial DO4TCALL at strange-context
*CLI> -- Executing [DO4TCALL at strange-context:1] Hangup("Console/default",
"") in new stack


*CLI> console dial EXIT at strange-context
No such extension 'EXIT' in context 'strange-context'

*CLI> console dial E8IT at strange-context
*CLI> -- Executing [E8IT at strange-context:1] Hangup("Console/default", "")
in new stack
*************************************************************************
*CLI> console dial ANSWER at strange-context
No such extension 'ANSWER' in context 'strange-context'
*CLI> dialplan set extenpatternmatchnew false
-- Switched to using the OLD pattern match algorithm for extension names
in the dialplan.
*CLI> console dial ANSWER at strange-context
*CLI> -- Executing [ANSWER at strange-context:1] Hangup("Console/default",
"") in new stack

Ah, I see what the issue is. I *blocked* that change from going into the
1.6.X branches instead of merging the change. That certainly explains why
you would see the problem there.
