"Moreover, in failure route you can only drop a reply, but you cannot failover."
I think this should say in reply route. Ben Newlin On 11/21/19, 3:56 AM, "Users on behalf of Răzvan Crainea" <[email protected] on behalf of [email protected]> wrote: Hello! By default, the replies received by OpenSIPS are relayed further, whether you have a reply of failure route or not. The purpose of these two routes is to do any processing on the messages they are processing. Note that the scope of failure route and reply route is a bit different: the reply route is ran for each reply message - this means that if you for example add a header on a 408, that 408 message will contain the header. Moreover, in failure route you can only drop a reply, but you cannot failover. The failure route has nothing to do with replies processing - it is ran in the context of the initial request. This means that if you add a header in failure route, it will not appear in any replies! However, if you run t_relay() in failure route, you will create a new branch - send the request to a new upstream - that request will contain the added header. The only thing that failure route running relates to replies is the fact that if you do a t_relay() in failure route and dispatch the request to a new destination, no reply will be sent downstream. To summarize, if you don't use reply route or failure route, all responses will be sent. The only exception to this rule is when you use parallel forking: send the initial request to multiple destinations in parallel. In such case, according to RFC 3261, OpenSIPS will only relay downstream the result all replies received from upstream - that is the lowest terminal response code.
