<div dir="ltr">Hi Fuad,<div>without going too far in kamailio's internals, a resume route is equivalent to a failure route and, as such, it operates on a "fake" fresh message. </div><div>One solution is to use msg_apply_changes() but my general advice is that all headers and sdp mangling (aka rtpengine invocations) should be done in branch routes, especially if your routing logic includes async routes/failure routes.</div><div><br></div><div>Federico</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Mar 28, 2022 at 1:20 PM Fuad Trle <<a href="mailto:trle.fuad@gmail.com">trle.fuad@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Henning,<div><br></div><div>I have tried this, but without success. <b>This function can be used from REQUEST_ROUTE or core REPLY_ROUTE.</b> t_newtrans & http_async_query force me to enter a new routing block and call fail with "500 I'm terribly sorry, server error occurred (1/TM)".
