[asterisk-bugs] [JIRA] (ASTERISK-23927) pbx_config do incorrect matching if - happens

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=219856#comment-219856 ] 

Richard Mudgett commented on ASTERISK-23927:
--------------------------------------------

This does not appear to be a bug.  The CLI "dialplan show [[exten]@context]" command shows *all* extensions that could match the given value.

Both patterns match the test extension "RG-600-7987111111501#@testr" you have given.  The _RG-6007-X. pattern is the better match because the 7 in the pattern is more specific than the X in the other pattern.  The _RG-6007-X. extension pattern will be selected when the dialplan is executed.

Please see

The dash (-) character is ignored in extensions and patterns except when it is used in a pattern to specify a range in a character set. It has no effect in matching or sorting extensions.

> If dialplan have context like this:
> [testr]
> exten =>_RG-6007-X.,1, NoCDR(6007)
> exten =>_RG-600-X.,1, NoCDR(600)
> Result of dialplan matching will be 
> dialplan show RG-600-7987111111501#@testr
> [ Context 'testr' created by 'pbx_config' ]
>   '_RG-6007-X.' =>  1. NoCDR(6007)                                [pbx_config]
>   '_RG-600-X.' =>   1. NoCDR(600)                                 [pbx_config]
> Resulting match of incorrect dialplan row.
> Issue is critical becuase such dialplan used by freepbx 2.6+ versions for ringgroups.
