[SR-Users] 180 and 183 SIP messages

[Ali Taher]

Thank you Alex for your response.

So if I want to add a header to the INVITE packet , and also  detect if the message is 183 and then change it to 180 then forward it back , does is do the job :

route{
if (is_method("INVITE"))
                {  	
append_hf("Test: this is a test");
}
forward(127.0.0.1,5060);
}
reply_route {
    if (status == "183") {
        change_reply_status(180, "Ringing");
        exit;
    }
}

Regards,
Ali Taher

You can absolutely do it:

https://kamailio.org/docs/modules/5.1.x/modules/textopsx.html#textopsx.f.change_reply_status

You can even remove the embedded SDP if desired, using the various textops functions:

https://kamailio.org/docs/modules/5.1.x/modules/textops.html

Whether you _should_ do this just because you _can_, on the other hand, is a question I would consider very carefully.
