[asterisk-users] Possible bug (or feature?) in extension matching and parking feature

[Noah Engelberth]

My understanding regarding the pattern match order is that Asterisk will not search include=> contexts unless there is no matching extension in the "original" context.  So, since _X. matches anything, the include=>parkedcalls context will never be searched.

A better way to accomplish what you want to do is to use exten => i (the Asterisk reserved extension for "invalid") to catch mis-dialed calls.  That way Asterisk will search for correct extensions in the original context, then search your include=> contexts, then fall through to exten => i if nothing matches.  And the i DOES need to be lower case.

Subject: [asterisk-users] Possible bug (or feature?) in extension matching and parking feature

I wanted a custom extension to match miss-dialled numbers in my dialplan. I've included the following:

exten => _X.,1,Answer()
exten =>
_X.,n,Playback(extension_not_found_please_make_sure_you_dial_nine_in_front_of_external_numbers)
exten => _X.,n,Hangup()

However, this has the curious side effect of making the parking extensions (located at 700, 701-720 - as per defaults) invisible. For some reason Asterisk doesn't seem to include those extensions on an even footing with extensions in the local context when extensions matching, although they are included with "include => parkedcalls". I can't park calls by transferring them to 700, I can't reach calls parked with the one step dialling sequence (which continues to work) any more.

My understanding is the * would match the most specific extension first
- but it would appear that this doesn't apply to parking extensions. All other extensions work fine when using the custom extension above.

I'm running Asterisk 10.1.2
