(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:

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");

                fix_nated_contact();
                setflag(5);
        }
    if(uri==myself) {
    	exec_dset("/usr/local/ser/bin/getroute");
    	route(1);
    }
