Regexp is used to allow/deny CallerID/Destinations for Origination Points, Termination Points, and Dial Peers.

Basic Regexp operators and building blocks are explained here.

Regexp Explanation
.* everything
^[0-9]+$ only digits
^[0-9]{9,}$ only digits, number more than 8 digits (9, 10, 11...)
^[0-9]{0,9}$ only digits, number less than 9 digits (1, 2, 3, 4, 5, 6, 7, 8)
^\\+?[0-9]+$ optional + sign and only digits
^370[0-9]+$ only digits starting with 370
^370.*$ anything starting with 370
^(37[0-1]|44)[0-9]*$ only digits starting with 370 or 371 or 44
^380(67|97|68|98)[0-9]*$|^998[0-9]+$ only digits starting with 380(67,97,68,98) or 998(0-9), where 380(67,97,68,98) = 38067,38097,38068,38098 and 998(0-9) = 9980,...,9988,9989.
^380(67|97|68|98)[0-9]{5,9}$|^998[0-9]{5,9}$ only digits starting with 380(67,97,68,98) or 998, but number of digits after each prefix should be between 5 and 9. So, for example, 3809712345 will match, but 380971234 or 380971234567890 will NOT match.
^370[138][0-9]+$ only digits starting with 3701, 3703, 3708
^/.*/999\1/ Add 999 in front of any string
