[Freeswitch-users] Matching plus sign in dialplan Regexp

Hello folks, I am actually using a regexp such as ^(\d{7,15})$ to route call to one of my gateway. My SIP clients have all their number registered with number such as +33123456789 Is there a way to treat the "+" and transform It in "00" at the level of FreeSwitch (I can do that at the client level, but you'll understand that It is easier to do on the server side). Thanks. ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ Gregober ---> PGP ID --> 0x1BA3C2FD bsd @at@ todoo.biz ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
