This is the regular expression I use to match phone numbers like:
00 00 00 00 00 00 00 0 00 00 00 00 +00 0 00 00 00 00 (\\d{2}\\s+\\d{2}\\s+\\d{2}\\s+\\d{2}
Escaping the parenthesis turns them into literals. Try it without the escapes:
/^(\d{2}\s+\d{2}\s+\d{2}\s+\d{2}\s+\d{2})\s+(\d{2}\s+\d{2}\s+\d\s+\d{2}\s+\d{2}\s+\d{2}\s+\d{2})\s+(\d{2}\s+\d\s+\d{2}\s+\d{2}\s+\d{2}\s+\d{2})/
