[asterisk-users] Dialplan "or" matching

[David Cook]

Maybe I'm daft, but can asterisk to 'or' logic in dialplan matches sort 
of like the SPA's can?

Tollfree numbers for example. I can have a line for each combination:
exten => _1800NXXXXXX, Dial, ............
exten => _1866NXXXXXX, Dial, ............
exten => _1877NXXXXXX, Dial, ............
exten => _1888NXXXXXX, Dial, ............

But I want to do is something like this:
exten => _18[0678][0678]NXXXXXX, Dial, .............

Or to prevent the logic error which albeit small, the above would create:
exten => _18[00,66,77,88:2]NXXXXXX, Dial, ......
(representing that the next 2 chars must equal any of '00'.'66','77' or 
'88'

Is there any syntax that allows this??
