[OpenSIPS-Users] Dialplan issues: simple strip\prefix cases

[Brett Nemeroff]

Bogdan,
Not to sound too dense here, but I don't get:
^(*4224*)(.+)

If you really wanted to match exactly 4224 wouldn't you just do:
^(4224)(.+)

Alternatively, with the OP requested, isn't it more like:
^([0-9]{4})(.+)

Maybe your *'s are for emphasis and not an expression? :) or perhaps
I'm rusty on my regex. :)
