[tracker] Comment added: Received replies should get higher preference than locally generated ones

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#54 - Received replies should get higher preference than locally generated ones User who did this - Iñaki Baz Castillo (ibc) ---------- Regarding the invented response: I would always prefer a timeout over some 500 a downstream proxy might have sent (the 408 says at least that there might be a working phone, but the user didn't pick it up). If gw1 doesn't send a reply (neither a provisional) then fr_timer expires and creates a local 408. Of course this 408 means nothing about "there might be a working phone, but the user didn't pick it up". So I'd strongly prefer the 500 received from gw2. Please check also the report [[http://sip-router.org/tracker/index.php?do=details&task_id=55&project=1|rep… 55]] in which I suggest a solution for locally generated responses. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=54#comment71 You are receiving this message because you have requested it from the Flyspray bugtracking system.

[tracker] Task opened: Improving logging (show at least the transaction branch)
by sip-router 30 Mar '10

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Iñaki Baz Castillo (ibc) Attached to Project - sip-router Summary - Improving logging (show at least the transaction branch) Task Type - Improvement Category - logging Status - Assigned Assigned To - Andrei Pelinescu-Onciul Operating System - All Severity - Low Priority - Low Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - Sometimes I inspect the log of SR/Kamailio and find errors like: ERROR:nathelper:force_rtp_proxy: incorrect port 0 in reply from rtp proxy or: WARNING:dialog:dlg_onroute: unable to find dialog for BYE with route param '7b4.36497575' [1207:1465357411] Of course in a server with high traffic such logs help nothing (even if I'm capturing all the SIP flow via pcap or 'siptrace' module). It would be great if the logging core system would log always "something" related to the request or transaction, perhaps the branch, something as: ERROR[recv 183 z9hG4bK6887.92b352f.0]:nathelper:force_rtp_proxy: incorrect port 0 in reply from rtp proxy WARNING[sent BYE z9hG4bK68612qwre1h3]:dialog:dlg_onroute: unable to find dialog for BYE with route param '7b4.36497575' [1207:1465357411] It would help a lot when debugging occasional issues (perhaps more related to a specific client rather than the SR/Kamailio server).

Re: [sr-dev] [Kamailio-Users] Fast lock loop with arm
by Daniel-Constantin Mierla 30 Mar '10

30 Mar '10

Hello, what version of kamailio do you use? Can you grab a backtrace with gdb once you get this high cpu usage? Spot one of the processes, take the pid and do: gdb /path/to/kamailio _pid_ Then: bt You should see the bactrace of executed function getting to deadloc. Make sure you get at least one SIP worker process backtrace (do kamctl ps to see the type of kamailio process).

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#54 - Received replies should get higher preference than locally generated ones User who did this - Andrei Pelinescu-Onciul (andrei) ---------- Alex, DNS failover is automatically attempted if a 503 is received or on timeout (just making sure that you don't try to do in script something that is already automatically handled). I guess your example is valid if you don't want to do DNS failover on the local proxy, but on the upstream one. Regarding the invented response: I would always prefer a timeout over some 500 a downstream proxy might have sent (the 408 says at least that there might be a working phone, but the user didn't pick it up). For 4xx responses is not so clear, it's debatable if one should prefer a 408 over a 480 or even a 486. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=54#comment69 You are receiving this message because you have requested it from the Flyspray bugtracking system.

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#54 - Received replies should get higher preference than locally generated ones User who did this - Alex Hermann (axlh) ---------- Andrei, making the priorities configurable would be a nice addition. For the example I gave with DNS based failover an even simpler solution is possible. In the DNS failover case i'm only interested in the replies from the last contacted host. Because the other hosts already gave responses i'm not interested in, hence the failover to the next host. So an option to only consider replies from the last host (branch) would (also) be a nice solution. I could use that in other cases too, because in general, i'm only interested in the responses from the last branch (but that might be related to my specific use cases). The question i asked myself is: why would i prefer a (invented) response from a host that __fails__ above the response from a responding host. I couldn't find an anwer... ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=54#comment68 You are receiving this message because you have requested it from the Flyspray bugtracking system.

about dp_translate()
by jh＠tutpro.com 29 Mar '10

29 Mar '10

currently, dialplan module dp_translate() function requires src/dest style second parameter even in cases where a dialplan id consists of rules where subst_exp and repl_exp are missing, i.e., when dp_translate() is only used for matching and possibly setting of attrs avp. how about if i try to change the syntax of second param to be src[/dst] if /dst is missing then no replacement is done? -- juha
