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 examples for matching
| 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 |
Regexp examples for transformation
| Transformation | Original number | Modified number | Comment |
| /^00// | 003701234567 | 003701234567 | Cut prefix 00 |
| /^370/8/ | 370123456789 | 8123456789 | Replace 370 with 8 |
| /\+// | +370123456789 | 370123456789 | Cut + (here + is escaped by \ since it is special regex symbol) |
| /\+370/86/ | +370123456789 | 86123456789 | Cut prefix +370, add prefix 86 |
| /\+?(.*)/+\1/ | 370123456789 | +370123456789 | Add + if it is not present already |
| ^/.*/999\1/ | 370123456789 | 999370123456789 | Add 999 in front of any string |
