7 Apr 2004

Hello,

I have small problem with dinamic routing.. my config looks like:
(page down)

as u see i have two steps routing.. second exec_dset return me uri of
voicemail or it could be another number. the question is:

how can i do rtp_proxy on second step ? i can not just put
force_rtp_proxy(); in failure_route.. it is not allowed....

Please help

short version:

route {
       if (nat_uac_test("2")) {
                xlog("L_ALERT", "(%ci) src address different than via
header->NAT detected");
                force_rport();
                fix_nated_contact();
                setflag(5);
        }
	if(uri==myself) {
		exec_dset("/usr/local/ser/bin/getroute");
		route(1);
	}
}
