Packet processing order
by Jawaid Bazyar 06 Dec '22

06 Dec '22

Hi, I have experienced out of order packet processing when testing a simple Kamailio config. The configuration is as follows, basically: request_route{ record_route(); enum_query(); xlog("INVITE ENUM query - To URI $tU"); forward(); } I saw this thread from 2020: https://www.mail-archive.com/sr-users@lists.kamailio.org/msg11786.html The issue seems to be that kamailio process scheduling is naïve – i.e., incoming SIP packets are processed without regard to whether packets received before this one, are currently being processed. This means any packets after the initial INVITE that require more processing, can get reordered. In my test lab I have: SIPp – UAC Kamailio Proxy SIPp – UAS The proxy uses enum NAPR lookups to route calls to +13038151000 to the UAS. Now, if I do SIPp UAC o SIPp UAS directly, I have no problems – no out of order packets. It is only when I introduce Kamailio in the middle that I get OOO packets. See the images attached: uac-to-proxy, proxy, and proxy-to-uas. In this example, Kamailio OOO causes SIPp UAC to fail to “generate audio” – because UAC does not see packets in the correct order, I never turns on the simulated audio. Calls that have in-order dialogs, work fine, and SIPP UAC “pauses” 10 seconds to simulate a phone call. So far, the error rate runs from 1/1000 to around 1/200 – pretty bad. In the thread, a few things were suggested. Have fewer kamailio processes than cores: Did not resolve issue. Try route_locks_size = 256 Did not resolve issue. Though, it did alter it somewhat. But, it is not clear to me how this works – would this setting restrict the number of open calls to 256? Have only one kamailio process: (“children=1”) This works. “Works”, I should say, because this would greatly restrict total platform scalability to a point where it is probably useless for my application. I saw the same issue discussed in the OpenSIPS mailing list from 2010, and the response was “this is not a bug”. Well, I respectfully beg to differ with both OpenSIPS and Kamailio – it IS a bug. I don’t think a proxy should reorder packets involved in a call in a non-deterministic way. In the Kamailio list thread, Alex Balashov discusses the contortions he has to go through to avoid repercussions from this issue. Kamailio as-is probably works fine for relatively low-volume operations. And a lot of the feedback is “why are out of order packets a problem?” OK, sure, in the very specific example given in the 2020 thread, maybe who cares. But in my thinking, there is absolutely nothing preventing Kamailio from generating much more serious OOO scenarios that would cause calls to fail. In my example, Kamailio OOO causes SIPp to fail to “generate audio”. Who knows how other SIP stacks will behave? But the more one will try to scale Kamailio, the more significantly this out of order processing issue will become. The solution to this seems very simple and straightforward – put packets to be processed into a queue PER Call-ID, or something along those lines. In short, the parallelism should be by call, not by packet. What say ye? Have I misunderstood something here? Cheers, Jawaid

Database Failure Detection at runtime
by Waqar 40 06 Dec '22

06 Dec '22

Hello Everyone, I am using Kamailio sqlops module to write to a remote database which is not the database of Kamailio. It is working fine. But for redundancy purpose, if this database goes down, I want the Kamailio to detect the failure at runtime and write the data to another database (standby database). Is it possible? Can anybody please guide me on this asap? Regards, Vicky

ds_is_from_list not matching dispatcher listed with hostname
by Benoît Panizzon 03 Dec '22

03 Dec '22

Hi On our devevelpment system, we have this dispatcher list: 3200 sip:reg1.dev.example.com:5060 0 0 name="Registrar01"; 3200 sip:reg2.dev.example.com:5060 0 0 name="Registrar02"; The names or course are in the DNS: A,AAAA and PTR. ds_is_from_list() returns the groupId 3200 Now I have started building the production system... 3200 sip:reg1.prod.example.com:5060 0 0 name="Registrar01"; 3200 sip:reg2.prod.example.com:5060 0 0 name="Registrar02"; DNS ist set up the same. I have double-checked: Names and IP addresses do resolve as they should. ds_is_from_list() returns nothing. I have also sniffed the connection. The ip addresses in the packets are the ones I expect. modparam("dispatcher", "ds_ping_from", "sip:survivability@sip.example.com") pings the machines and is getting answers. What else could cause this not to match? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

imc sends all messages with Content-Type: text/plain
by Joey Golan 02 Dec '22

02 Dec '22

Hello, I'm checking the imc module and it appears that imc sends all messages with hard-coded content type header so if client sends an application/im-iscomposing+xml message, other clients receives the message with content-type text/plain which is very confusing. I think the right behavior is to take the content-type header from the original message and use it in the messages imc sends. Is there a workaround that might help me achieve that?
