If you're always trying to catch "555" for the prefix, instead of playing
with pattern matching the extension, you could test on the substring:
exten => _1NXXNXXXXXX,1,GotoIf($["${EXTEN:-7:3}" =
"555"]?outbound-411,411,1)
This example would match any "1+Area code+number where the prefix is "555".
You could play with your pattern match to catch call to 1+AC+Number and
just AC+Number using this same test since it's right-delimited.
