[SR-Users] Manipulate From URI username

Hello Kamailions, Im trying to manipulate the username from the from uri, but not having any luck, I must be doing something wrong. I receive a from uri username that is prefixed with 888, now I am trying to remove the triple 8. I have configured the following: line 1090 if($fU=~"^888"){ 1091 strip(3); 1092 } 1093 route(GETGROUP); But I do not get any result, the debug shows the following: 29(9610) exec: *** cfgtrace:request_route=[MOMANX] c=[/usr/local/etc/kamailio/kamailio.cfg] l=1093 a=16 n=if 29(9610) exec: *** cfgtrace:request_route=[MOMANX] c=[/usr/local/etc/kamailio/kamailio.cfg] l=1091 a=45 n=strip 29(9610) exec: *** cfgtrace:request_route=[MOMANX] c=[/usr/local/etc/kamailio/kamailio.cfg] l=1093 a=5 n=route Does anyone see what I am doing wrong? Help would be appreciated. Rgds, Gertjan Wolzak
