Hi
I have following scenario:
u1---> p1 --> u2
u1 calling u2, u2 reply with 200 OK,
The p1 need to check something, and decide to send ACK/Bye to u2,
and 488 to u1:
onreply_route[1]
{
if (my_function_check("")) {
release_call_onreply("");
}
}
The question is : How to do implement release_call_onreply correctly?
The pseudo codes is like:
t=tmb.t_gett();
send_request(method_ACK);
send_request(method_BYE);
reason_code = 488
tmb.t_reply(t->uas.request,reason_code,reason_text);
(Not sure if t_reply can be called here or not.)
The ACK/Bye is sent to U2, 488 is sent to U1,
But the issue is it seems the original 200 OK is forwarded to U1 as
well.
How to avoid it?
You need either to DROP the reply (add drop in the script after your
function), or use the generic onreply_route ( [0] or unnamed).
Anyway you would need to modify t_reply, or it won't work from the
onreply_route (at least not in sr 3.*).
Or should the Data lumps function be used here to modify the 200 reply
msg instead of using t_reply here?
No, you won't be able to change the reply code that way.
