using myself in equation with from_uri
by Dirk Teurlings - SIGNET B.V. 25 Jan '16

25 Jan '16

Hi, The documentation states the following. https://www.kamailio.org/wiki/cookbooks/4.2.x/core#myself if(uri==myself) { log("the request is for local processing\n"); }; Now this could also be used to do something like this: (also used in some examples) if(from_uri==myself) { log("the request is for local processing\n"); }; Using this the from_uri could be: sip:sip.voipexample.net:5061 myself in this case only has sip.voipexample.net:5060 as an Aias Now the equation wouldn't match, … [View More]

Fosdem 2016
by Daniel-Constantin Mierla 22 Jan '16

22 Jan '16

Hello, anyone going to Fosdem? If no unexpected weather conditions messing the transport system, I am going to be there. It would be good to know who else we can meet there. If there are enough people interested, we can try organizing a social event (dinner/drinks) on Saturday evening. Last year we did it together with Jitsi team, but they are not coming this year. Perhaps there are other folks around the RTC dev room we can ask. On the other hand, it is harder to find a place if it is a … [View More]

Kamailio and openLDAP integration.
by Safdar Khan 22 Jan '16

22 Jan '16

Hi guys, I have tried to integrate kamailio and ldap.It seems like both are taking to each other. Here the purpose of ldap is for back-end support for sip user authentication rather than kamailio database.However i am able to log in but could not make call between sip users.I could not figure out what i am missing. Here is the routing block for ldap in my kamailio.cfg > request_route { > route(LDAPAUTH); > > } --- route[LDAPAUTH] > { > if(is_method("REGISTER")… [View More]

SIP Trunking using Kamailio IMS
by indranil chowdhury 21 Jan '16

21 Jan '16

Hello, Is SIP trunking possible with the free version of Kamailio or we need to upgrade to business license? Kindly get back to us with the details of using SIP trunking using Kamailio. We have a requirement in our organisation regarding the same which uses IMS and SIP trunking. In this setup we would initially like to test with 2 LTE EPCs connected to two Kamailio IMS with a SIP trunk between them. Thanks and Regards, Indranil

topoh quirk with 200 OK for CANCEL
by Alex Balashov 21 Jan '16

21 Jan '16

Hi, I'm using topoh and am running into lots of these errors: Jan 19 20:34:52 csrpus1 /usr/local/sbin/kamailio[3641]: ERROR: [R-DEFAULT-STATELESS-REPLY:nmhfrms2ib9Cnm9kS00Qtbtot5PMiQ0Ni1QKS5iKibuotel14Ygc] !> Received stateless reply 200 (CANCEL) from xxx.xxx.xxx.xxx:5060 Jan 19 20:34:53 csrpus1 /usr/local/sbin/kamailio[3639]: ERROR: tm [t_lookup.c:932]: t_reply_matching(): matching transaction found but callids don't match (received: … [View More]nmhfrms2ib9Cnm9kS00Qtbtot5PMiQ0Ni1QKS5iKibuotel14Ygc stored: 51899BC6-569EE4330005CE1B-7D47C700_bleg) The call topology is: UAC --> Kamailio (+ topoh) --> PSTN GW Topoh is behaving precisely as expected, but it looks like we might have hit a TM case that topoh does not accommodate somehow: 1. A CANCEL comes in from the UAC and Kamailio sends a CANCEL for its branch to the PSTN GW. 2. Kamailio sends a '200 cancelling' for the UAC's branch backward. 3. The PSTN GW replies with a 200 OK for the CANCEL (PSTN GW branch) that contains the topoh-spoofed Call-ID, but for some reason Kamailio does not match this reply, as indicated by the above error. 4. Because the 200 OK reply was stateless and not matched to a CANCEL transaction, this causes Kamailio to retransmit the CANCEL to the PSTN GW, at which point it receives: 481 Call Leg/Transaction Does Not Exist 5. #4 repeats once more. I don't see any real harm from this situation, but it seems like something that needs fixing. The 487 Request Terminated final reply is processed and relayed correctly to the UAC, and the dialog ends appropriately everywhere. FWIW, I thought this might have to do with async processing of the initial INVITE (through mqueue + rtimer), so I turned it off, but it didn't make any difference. My CANCEL handling in the main request route looks like this: if(is_method("CANCEL")) { set_rtpengine_set("1"); rtpengine_delete(); if(!t_relay_cancel()) { sl_send_reply("500", "Internal Server Error"); exit; } xlog("L_ERR", "[R-MAIN:$ci] !> " "Corresponding INVITE transaction for CANCEL " "does not (or, no longer) exists\n"); exit; } So, it just looks like TM is not matching, and therefore not absorbing the 200 OK reply to its CANCEL to the upstream gateway -- when topoh is enabled.

RFC: removing (disabling) fork=no
by Daniel-Constantin Mierla 21 Jan '16

21 Jan '16

Hello, wondering if anyone is using fork=no -- some old docs suggest it is suitable for debugging, but actually kamailio doesn't work properly in this mode, leading to more troubles than benefits (e.g., having reports of invalid issues, like tcp not working in this mode). In first phase I would disable setting this value, with a warning if set to no, because most of the configs out there have fork=yes. Removing it could be considered in the future. Note that this fork=no is different than … [View More]

Re: [SR-Users] Fwd: Kamailio and NAT
by Nelson Migliaro 20 Jan '16

20 Jan '16

I am thinking that I cat get the port during the first call and then use that port for the rest of calls. Maybe that first call will fail but after that, all calls will go fine. Example of a Trying showing received port: 52548 ¿Do you know what pseudovariable represent that value? I tested with all variables I could find but I could not find anyone. Thank you -------------------------------------------------------------------------------------------------------------------------------------… [View More]

Registration to sip provider
by Evren Akbulut 19 Jan '16

19 Jan '16

Hi, I am a newbie. As I read I understand I need to use UAC module for registration but cannot figure how to trigger the registration request. I enable the UAC module and it seem to be working. How can I trigger the REGISTER to a SIP provider account? And is it possible to use multiple accounts for different provider registrations? Can someone help about UAC usage please. Regards Evren Akbulut
