Right, but with [] syntax, we need to parse prefix strings and calculate their length/compare with other strings in a special way. For now, I'll add something like:
! - to disable prefix (like !0048) . - to match any character
We'll see how it works and later (when I have more time) we can extend this format with [].

We sort all prefixes by their length and then select the longest matching. With arbitrary regexps this is a problem to decide, what "the longest" match means. But maybe we can have something simple, like: 0-9 - match exact digit . - match any digit, # or * # - match # * - match *
With this, there is no problem with the longest match.
Cisco's dial-peer patterns are also based on the longest match. Maybe something simple can be used like 003[3-5].. Or 004[!1-7].....
This won't violate the routing logic by the longest match.
