[Freeswitch-users] FreeSWITCH-users Digest, Vol 93, Issue 198

Mon Mar 31 20:53:41 MSD 2014

Hi All,

I'm trying to use freeswitch International country codes regular expression
in my lua script, but i keep getting this error:

unexpected symbol near '/'
stack traceback:

here is the regular expression I'm trying to use:

"^\+(1|2[1-689]\d|2[07]|3[0-469]|3[578]\d|4[0-13-9]|42\d|5[09]\d|5[1-8]|6[0-6]|6[7-9]\d|7|8[035789]\d|8[1246]|9[0-58]|9[679]\d)(\d+)"

I've tried using this also:

"^\\+(1|2[1-689]\\d|2[07]|3[0-469]|3[578]\\d|4[0-13-9]|42\\d|5[09]\\d|5[1-8]|6[0-6]|6[7-9]\\d|7|8[035789]\\d|8[1246]|9[0-58]|9[679]\\d)(\\d+)")

link: https://wiki.freeswitch
.org/wiki/Regular_Expression#International_country_codes

what should i change?

Thanks,
Snabel
