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

by sip-router

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.

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#53 - wrong TM response code User who did this - Andrei Pelinescu-Onciul (andrei) ---------- Yes, it did, but on the lo interface (that's why it's not in the ngrep dump). First of all you can see that the INVITE forwarded back to 83.136.33.3:5200 it's on the second branch (branch number 1 and not 0): Via: SIP/2.0/UDP 83.136.32.159;branch=z9hG4bK404.f2951c02.1 (note the .1 at the end) Then looking at syslog.txt: Mar 26 13:41:58 plaudertasche /usr/sbin/kamailio[30989]: INFO: <script>: 3df971d27197-l2satt3hm9s8@83-136-33-3 appending branch to gateway ... .....

The proxy receives the INVTIE for sip:00123456@labs.nic.at, and the auth. fails (the credentials are probably removed in the script before forwarding, but even if they would not be removed they would be for klaus.darilion and not for 00123456): Mar 26 13:41:58 plaudertasche /usr/sbin/kamailio[30990]: INFO: <script>: 3df971d27197-l2satt3hm9s8@83-136-33-3 authentication failed, wrong or missing credentials, challenging... .... Mar 26 13:41:58 plaudertasche /usr/sbin/kamailio[30990]: DEBUG: sl [sl.c:318]: reply in stateless mode (sl) Then the proxy will reply with 407 for the INV to sip:00123456@labs.nic.at, on the lo interface (that's why it's not in the ngrep dump). In the end there are 2 responses for the INV transaction: the 407 and the 482 and the proxy chooses the 407. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=53#comment54 You are receiving this message because you have requested it from the Flyspray bugtracking system.

I have a strange scenario where TM forwards the wrong response code: client A proxy ---INV A----------> <--407------------- ---ACK------------> ---INV A----------> <--------INV A----- ---------482 loop-> <--407------------- ^^^^ bug: should be 482 I made same tests: It does not happen always. In the scenarios where I had this problem the caller called himself. Log is attached. I used today's kamailio-3.0 from git (2010-02-26) One or more files have been attached.
