<div dir="ltr">Alex,<div><br /></div><div> I am not sure of your use case - but one common example I can think of is a <span class="">LRN</span> service provided via 302 redirect. What we do in this instance is <span class="">UAC</span> -> <span class="">Kamailio</span> on this initial transaction we send the call directly to the <span class="">LRN</span> service (not appending) any other branches and alter the original state of <span class="">ruri</span>, we then set a special reply route that receives the <span class="">LRN</span> information, caches it in a database so subsequent requests entirely avoid this process for a period of time since its already cached. We also set a custom failure route that appends the new branch(s) upstream back to <span class="">LCR</span> / <span class="">PSTN</span> using <span class="">LRN</span> information. Now with this said - while the transaction is in flight upstream, and a cancel from <span class="">UAC</span> is sent, simply
flag the transaction / response you receive back from upstream and drop it in the reply.</div>
