Describe the bug append_to_reply not working when t_reply_with_body is used inside a failure_route block. Only the body is present in the reply.

To Reproduce

failure_route[local_reply] {
    t_reply_with_body(404, "Not Found", "a b c"); 
    append_to_reply("Foo: bar\r\n");

Expected behavior

A sip reply with Foo: bar header and a body with content "a b c".

Relevant System Logs no errors found in the opensip log.

OS/environment information

• Operating System: Almalinux 8
• OpenSIPS installation: official rpm packages

A similar issue was fixed in the past for request route

[Riccardo-78]

adding update_cloned_msg_from_msg( t->uas.request, msg); to w_t_reply_body for the FAILURE_ROUTE case fix the issue.

[bogdan-iancu]

Isn;t the order of the operations the other way around, like first adding the hdr to reply and then sending the reply, like:

failure_route[local_reply] {
    append_to_reply("Foo: bar\r\n");
    t_reply_with_body(404, "Not Found", "a b c"); 
}

[Riccardo-78]

It doesn't work even if I put append_to_reply before t_reply_with_body
