The network trace will help in this case. Seems that the reply coming from GW has only one Via header, while all replies should have at least 2 Via headers if the request was not initiated by OpenSER.
Cheers, Daniel

Hi,
thanx for taking the time to answer.
the scenerio i have is like this
openser sends all numbers that are not registerd to it to a special GW. the special GW then responds w/ a 302 redirect providing the correct route info for that number. i need openser to take the info from the 302 and resend the invite to the address in the 302 (contatct field).
i am using a cfg from the uac_redirect sample to make it as simple as possible.
w/ openser debug=7 i see the following :

the cfg is as follows:
route{ if (uri==myself) {
if (method=="REGISTER") { save("location"); exit; }; if (!lookup("location")) { # sl_send_reply("404", "NotFound"); # forward( 212.25.94.16, 7777); rewritehostport ("212.25.94.16:7777"); t_relay(); exit; };
} else { # just do redirect t_on_failure("1"); } if (!t_relay()) { sl_reply_error(); }; } failure_route[1] { get_redirects("*"); t_relay(); }thanx again for your time.
