[sr-dev] [tracker] Task opened: Received replies should get higher preference than locally generated ones

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Alex Hermann (axlh) Attached to Project - sip-router Summary - Received replies should get higher preference than locally generated ones Task Type - Bug Report Category - tm Status - Assigned Assigned To - Andrei Pelinescu-Onciul Operating System - All Severity - Medium Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - In the current version, the reply with the highest priority (lowest response code) gets forwarded. At least in a situation with DNS based failover this can be unwanted. When I have 2 hosts in a failover situation and the first is offline, a local 408 is generated. If the 2nd host responds with a higher response-code, the 408 gets forwarded. If the 2nd branch responds, it would be more logical to forward it, as it has information on the callee. If the callee responds 603, the upstream proxy or caller may want to do failover based on that code. If it always received 408, this is impossible. Suggested fix: forward the highest priority _received_ response. optionally, make this behaviour configurable. Standards complicance: the rfc's talk about _forwarding_ the highest priority response. This implies it should have been _received_ by the proxy. A proxy should only 'invent' replies if there are no other options left.
