Next online devel meeting - Wed, Apr 29, 2020, 14:00UTC
by Daniel-Constantin Mierla 29 Apr '20

29 Apr '20

Hello, in order to plan the roadmap to next major release, it is time to organize another online devel meeting, so the developers and community members can syncronize and plan what should be done till Kamailio v5.4 will be out. Because freenode.net service is now requiring user registration to join IRC channels on their servers, we are considering some alternatives that would allow guest participation, one of them being using a matrix chat room. More details about it will be posted soon. I created a wiki page for the event at: * https://www.kamailio.org/wiki/devel/irc-meetings/2020a Feel free to add there topics that you want to be discussed. The proposed date is next Wednesday, April 29, 2020, at 14:00UTC (15:00 London/Dublin, 16:00 most of West Europe, 10:00 New York), but other dates can be proposed if they suit for more participants.

NAT and RTP
by Pavithra M 29 Apr '20

29 Apr '20

Hi, I have installed kamailio as a ims server in openstack and enabled WITH_NAT and rtpproxy . I have installed pcscf, icscf, scscf and hss in four different ubuntu instances . server - kamailio 5.3.3. When i make a call using zoiper client from external network , call is becoming a missed call without giving ACK and BYE. Openstack - pcscf - 10.40.10.3 (floating ip - 10.45.4.22) icscf - 10.40.10.12 scscf - 10.40.10.5 hss - 10.40.10.31 zoiper1 - 10.0.2.15 zoiper2 - 10.0.2.15 kindly help me in this regard. when i installed without using NAT and rtpproxy, the call went well. Since currently i am using Opensatck , it is my prerequisite to use zoiper client externally .so for me it is mandate to enable NAT and rtpproxy. Help me please!!!

DNS SRV issue
by Melek Oktay 28 Apr '20

28 Apr '20

Hi All, I have a user, who has a SRV records like below, srv:betaproxy.siptelekom.com 1- SRV betaproxy siptelekom 4 hrs 20 0 5060 beta-proxy-dc01.siptelekom.com (X.Y.87.150) 2- SRV betaproxy siptelekom 4 hrs 10 0 5060 beta-proxy-dc02.siptelekom.com (X.Y.87.160) And I want to send the call to him/her, but one of the potential IP address could be failed. Assume that, first record (X.Y.87.150) is failed when I'm trying to send the packet. Later on, timeout occurs and our Kamailio try to send the packet to second one (X.Y.87.160) after period ot time. My question: Next time when I want to send another call to the same user, how Kamailio could use second (X.Y.87.160) SRV instead of trying to first one (X.Y.87.150) ? What is the elegant way to implement this ? Best Regards, Melek

RTP relay
by hugues 28 Apr '20

28 Apr '20

Hello I'm trying to run Kamailio in front of an asterisk server due to security issues. Both servers have a public ip address. It works fine but the RTP voice traffic goes directly from the VOIP client to the asterisk server without going through the kamailio server. I want to shut down the asterisk server so that it only talks to the kamailio server. UA -> Kamailio public IP addr <-> Asterisk public ip addr How do I force RTP traffic to go through kamailio. Apparently I don't have NAT so I don't need rtpproxy. But you need something that relays RTP traffic? If anyone has an idea I'll take it. Thank you for your help. Hugues. -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html

DMQ broadcasting crashes kamailio
by SamyGo 28 Apr '20

28 Apr '20

Hi, Is there a way to broadcast KDMQ to the cluster but not expect a reply back !?as far as I've read the source code dmq_bcast_message is exactly like dmq_send_message in a way that it expects a callback to be executed on response i.e expects a reply. So, the situation I'm facing is I'm broadcasting message to cluster and I do not want a reply back. The following two options result in crash & core dump. 1 - If my script doesn't respond back, by use of dmq_handle_message, it marks the destined servers as "inactive" and stops usrloc sync process which isn't desirable. 2 - If I respond back with the dmq_handle_message it crashes the Kamailio which just received this broadcasted message. Here is how its done in script: *broadcasting message to cluster:* dmq_bcast_message("userOnline", "$fu", "text/plain"); *Receiving and handling a broadcast message:* route[DMQ_HANDLE] { if(!(is_method("KDMQ") || $rm == "KDMQ")) return; if(is_method("KDMQ") || $rm == "KDMQ"){ if($rU =~ "userOnline"){ //user came online in cluster, resume transactions if-any suspended $avp(remoteUser) = $rb; } dmq_handle_message(); exit; } } *Related log lines:* Apr 23 21:15:48 kamailio[916]: ALERT: <script>: [da2c1-2f499] ------ DMQ_HANDLE: UserOnline Event Received ------ Apr 23 21:15:48 kamailio[916]: DEBUG: dmq [message.c:53]: ki_dmq_handle_message_rc(): dmq_handle_message [KDMQ sip:userOnline@9.8.7.123:5060] Apr 23 21:15:48 kamailio[916]: DEBUG: dmq [message.c:66]: ki_dmq_handle_message_rc(): dmq_handle_message peer found: userOnline Apr 23 21:15:48 kamailio[916]: DEBUG: <core> [core/receive.c:437]: receive_msg(): request-route executed in: 401461 usec Apr 23 21:15:48 kamailio[935]: DEBUG: dmq [worker.c:87]: worker_loop(): dmq_worker [2 935] lock acquired and crash/segfault.. Core dump: https://pastebin.com/S7ekCPfF Any help or pointers to solve this would be really appreciated. Best Regards, Sammy

RFC: C standard requirements
by Daniel-Constantin Mierla 27 Apr '20

27 Apr '20

Hello, (cross-posting because it is relevant to know where users need to run Kamailio as well as what developers tend to use for coding, but replies can go to one or the other list). Somehow I tried to stay close to ANSI-C/C90 with C coding style, for the reason of being compatible as much as possible with old compiles and niche/embedded systems. But I noticed that there are couple of C99 extensions in the core, like inline functions, variadic macros (the debugging macros), use of 'long long' or line comments starting with "//" (not so many, but still such comment style is used). Although I haven't searched for occurrences in core, but I remember seeing designated initializers (or initializing a structure by field names). These are part of C99, as listed by: * https://en.wikipedia.org/wiki/C99#Design Although likely GCC had some of them like custom extensions before the standard was out. On the other hand, newer standard C11 made some of those extensions optional: * https://en.wikipedia.org/wiki/C11_(C_standard_revision)#Optional_features So, my email here is to figure out if we should consider C99 as the requirement for adding C code or be more restrictive because there are still cases of usage on very specific systems that do not have such C compiler. We can eventually make a list of what is accepted or not from the recent versions of C standard to stay as much as possible portable across Unix'es. >From develeopers perspective, it would be good to learn if they use (in other projects, etc.) extensions of the new standards that they found useful and simplify their programming work.

by Pavithra M 27 Apr '20

27 Apr '20

Hi, I have configured kamailio IMS in vm based images. I have configured pcscf,icscf,scscf,hss and ue in five different vms.I am able to successfully make a call via IMS. But when making a INVITE from alice to bob, it goes via ue -> pcscf pcscf -> scscf scscf -> icscf icscf -> scscf scscf -> pcscf (here multiple INVITE is happening and giving 483 Too Many Hops error and then the call is going to UE successfully) pcscf -> ue Can anybody help me what am i missing . why multi INVITE is happening there alone and giving me too many hops issue. Even after that issue how the call reaches the other UE. Kindly anyone help me in this regard atleast where to check this scenario.

Dialog module problem.
by Voip support 24 Apr '20

24 Apr '20

Hello, i am using dialog module in-memory to get all dialogs and show in a website. I use for this kamctl dialog show which is run quite often for autorefresh. I noticed that some calls get hung on kamailio while on caller side and callee side calls are disconnected. I captured a wireshark trace and for same caller IP i get many good calls as well some bad calls (not disconnected properly). When comparing the BYE packets i could not notice any difference. However in the "BAD" calls it looks like the BYE from caller get stuck on kamailio and is not sent/forwarded to callee side. I get BYE retransmissions from caller and all BYE requests got stuck on kamailio. After few seconds Callee side sends BYE and that BYE also get stuck. I am wondering how to trace this issue (differently than taking a wireshark trace) as i dont see any difference in the good BYE and the bad BYE. It looks like for any reason from time to time BYE is not forwarded to the other side and when the other side sents BYE its also not forwarded to call initiator. Please give me a clue how to continue on this. I am using dispatcher module to send the calls. Best regards Tom
