Hi, When I'm trying to update $ru, $fu & $fd in Kamailio conf: $rU = "1000"; $fu = "sip:something@mydomain.com"; $fd = "newdomain.com"; And later I'm trying to print out $rU, $fu, $fU & $fd in onsend_route: xlog("ALERT: From URI $fu \n"); xlog("ALERT: From domain $fd \n"); xlog("ALERT: From user $fU \n"); xlog("ALERT: Request user $rU \n"); Kamailio 4.3.3 prints out following: ALERT: From URI sip:2000@some_ip ALERT: From domain some_ip ALERT: From user 2000 ALERT: Request user 1000 But I believe it should: ALERT: From URI sip:something@mydomain.com ALERT: From domain mydomain.com ALERT: From user something ALERT: Request user 1000 I'm using default Kamailio config with minor changes, you can check it in attachment.
