Kamailio as TCP UDP proxy
by M K 05 Oct '18

05 Oct '18

Hi, I'm struggling with the configuration to use Kamailio as TCP UDP proxy: [SIP Client] <-(TCP)-> [Proxy] <-(UDP)-> [SIP Server] should be the setup. I only have one client and one SIP server. How do I get Kamailio configured as a proxy so that translation between TCP and UDP works (and vice versa)? I have not yet found any documentation and examples that have caused messages to arrive at my SIP server. I think I've been on the wrong track so far and I'm looking forward to any … [View More]

Development for Kamailio v5.2 series is frozen
by Daniel-Constantin Mierla 05 Oct '18

05 Oct '18

Hello, short note to mark the freezing of development for Kamailio v5.2 series. For few weeks, please do not push new features in the master branch. Once the branch 5.2 is created (expected to happen in 3-4 weeks from now), the master branch becomes again open for new feature. Meanwhile the focus has to be on testing current code. Work on related tools (e.g., kamctl) or documentation can still be done as well as getting the new modules in 5.2 in good shape, plus adding exports to kemi … [View More]

PATH when used with multiple listening ports
by Sergiu Pojoga 04 Oct '18

04 Oct '18

Hi again, When acting as an intermediary proxy for a non-colocated Registrar, the REGISTER request coming in on one port and going out on another, shouldn't the *add_path[received]()* generate *two* nodes in the Path header? Otherwise, how are the subsequent requests supposed to be routed back to the UAC? Scenario with Kamailio proxy on IP 1.1.1.1 with dual port listeners UAC => proxy:5070 <=> proxy:5060 => Registrar:5060 Path: <sip:1.1.1.1;lr;received=sip:123.123.123.123:… [View More]

Kamailio in a mobile world - ts_append issue
by Dan Quinney 04 Oct '18

04 Oct '18

Using "Kamailio in a mobile world" as a base, I have the following routes to store information about the current transaction, however, if the transaction is already cancelled registrations for the user will still trigger `ts_append`, raising an error as the htable hasn't expired yet. Is there anyway to remove the htable entry when the original transaction cancels? Or something else that I'm missing?

Roadmap to next major release - v5.2.0
by Daniel-Constantin Mierla 04 Oct '18

04 Oct '18

Hello, as it was discussed during our last IRC devel meeting before the summer, the time to release a new major version should be this autumn. With the Kamailio Developers Meeting planned for September 27-28, 2018, I think it is better to freeze the code couple of days after that event. So I propose the following milestones: * on Thursday, October 4, 2018 - last development day, code for 5.2.0 will be frozen at the end of the day * 4 to 6 weeks of testing * release … [View More]

Planing the release of Kamailio v5.1.6
by Daniel-Constantin Mierla 04 Oct '18

04 Oct '18

Hello, a matter of the schedule to be agreed in the morning and the availability during the Kamailio Developers Meeting, we may do a new stable release from branch 5.1.6 on Thursday, Sep 27, 2018, in the afternoon. Given that several of us will be in the same room, the special goal would be to try to automate the process as much as possible. If the time doesn't allow it, then the release will be done next week, a specific day to be decided by the end of this week. Anyhow, this is the … [View More]

What is the typical network setup for kamailio?
by Kevin Olbrich 03 Oct '18

03 Oct '18

Hi! I am working successfully with Kamailio in my lab setup where Kamailio is the SBC for Asterisk. The network layout is looking like this: SIP-Phone <== PUBLIC NET ==> Kamailio (SBC) <== PRIVATE NET ==> Asterisk <== PUBLIC NET ==> Carrier Each public network is reachable from the internet and has a local firewall with IP whitelists. The internal SIP transactions are UDP-only but for external phones I would like to also listen for TCP/TLS. For this layout to work with … [View More]

Hi! Which hostname do I need to request for the certificate when the servers are load-balanced using DNS-SRV? Do I need to get the cert for the DNS-SRV subdomain (without _sip._tls) or for the servers, eg. server0{1,2,3}.pbx.example.com ? Thank you! Kevin

Dialog lifetime for dialogs synced with DMQ
by jenus＠cyberchaos.nl 02 Oct '18

02 Oct '18

Hello, I'm using DMQ to sync dialogs between a active and standby kamailio node. I noticed that when the standby takes over dialog's they do not expire after the lifetime i set on the other node. Is there a way to make sure that calls are terminated after the dialog lifetime expires? I see that the timer is replicated to the other node, but nothing happens after the dialog expires. The event routes aren't executed as well. Thanks, Jan

Registrar Module

Hi, So, route[REGISTRAR_1] will, when the max_contacts is reached, reply to the endpoint with a 503 error containing a "P-Registrar-Error: Too many registered contacts" header - this seems wrong to me so I've tried to work around it with route[REGISTRAR_2] which returns the right response, but, also writes "INFO: registrar [save.c:615]: test_max_contacts(): too many contacts for AOR" to the log file, which is messy. Does anyone have any pointers for doing this better? Thanks, Dan route[… [View More]

RTPEngine Question
by Wilkins, Steve 01 Oct '18

01 Oct '18

Hello All, I have an issue where Kamailio-RTPEngine-Asterisk calls work good when a softphone UAC on an IOS phone makes an Inbound call to a WebRTC client. However, if the softphone UAC is on Windows, it does not work (No Audio/Video). I noticed in the Wireshark trace that when using IOS I see STUN packets, but when using Windows I see no STUN packets. I believe this may be my issue, but I am not sure why the IOS would create STUN packets but when using Windows I get no STUN packets. Does … [View More]

Hello, I have a issue with setting the dialog timeout for a call. It works fine until i receive a re-INVITE. The re-INVITE seems to reset the dialog timeout back to the default value configured in the module parameters (7200 in my case). I use "dlg_set_timeout("900");" to set the timeout to 900 seconds. When i receive a re-INVITE i see the following in the debug logs: DEBUG: dialog [dlg_handlers.c:647]: get_dlg_timeout(): invalid AVP value, using default timeout This happens even with … [View More]

Important: new module exports interface
by Daniel-Constantin Mierla 28 Sep '18

28 Sep '18

Hello, as a result of collaborative work at Kamailio Developers Meeting, we succeeded to merge the two existing module exports interface (one for kamailio modules and the other one from ser modules) in a single one. All public modules were updated, but if you have any private module then you have to update as well in order to get it compiled with the latest master. Just look at one of the modules (e.g., sl is a good option) and all the fields in mod exports structure have comments with their … [View More]

Hello guys, I'm following this guide: https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb And I have the following schema: Phone A -----> Kamailio -----> Asterisk -----> Phone B (10.0.8.249) (10.0.6.123) (10.0.3.144) (10.0.13.23) I think the flow it is like (because when UAC register to Asterisk, the contact points to Kamailio IP): 1. Phone A --> Kamailio --> Asterisk 2. Asterisk --> Kamailio --> Phone B … [View More]In attachment is the pcap of the call, kamailio config. The problem is that I never receive ACK after 200 OK and call drops after 30 seconds? Kamailio version 5.1 and Asterisk version 15.1 Phones are grandstreams and also tested with microsip soft client and same results... Like "Phone A" never sends ACK back I tried different approaches to change contact header in 200 OK, because is Asterisk IP. Disable NAT handling. Different "nat_uac_test" flags, but still without success :( Also tried with this NAT detection and manage routes (again without any success) - source https://github.com/sipwise/kamailio/blob/master/etc/kamailio.cfg # Caller NAT detection route[NATDETECT] { #!ifdef WITH_NAT force_rport(); if (nat_uac_test("19")) { if (is_method("REGISTER")) { fix_nated_register(); } else { if(is_first_hop()) { set_contact_alias(); } } setflag(FLT_NATS); } #!endif return; } # RTPProxy control and signaling updates for NAT traversal route[NATMANAGE] { #!ifdef WITH_NAT if (is_request()) { if(has_totag()) { if(check_route_param("nat=yes")) { setbflag(FLB_NATB); } } } if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return; if(nat_uac_test("8")) { rtpproxy_manage("co"); } else { rtpproxy_manage("cor"); } if (is_request()) { if (!has_totag()) { if(t_is_branch_route()) { add_rr_param(";nat=yes"); } } } if (is_reply()) { if(isbflagset(FLB_NATB)) { if(is_first_hop()) set_contact_alias(); } } #!endif return; } Thanks in advance Denislav Raychev Tsonev | Integration and Infrastructure Engineer | Musala Soft JSC www.musala.com | t: +359 2 969 58 21 | m: +359 878 270 965 | f: +359 2 969 58 22 World Trade Center, 36 Dragan Tsankov blvd., Sofia 1057, Bulgaria [View Less]

kamailio not forwarding 407
by David Villasmil 26 Sep '18

Hello guys, I have an almost default config, the box behind kamailio sends out the register, it is forwarded to the provider, which replies with 401, this gets forwarded back to the box which sends out the REGISTER with credentials and all works well. BUT when calling out, INVITE is sent to kamailio which is properly forwarded to the provider. The provider replies with a 407 and this 407 is NOT forwarded back to the box. Any ideas why?

Hey, I've been using the Dispatcher module with great results. But now, i want to be able to have some gateways to belong to more than one group set. To achieve that, i'm duplicating the Gateway in the Dispatcher's table and give it a different group set. However, if i do this, Dispatcher will do repeated probing to this gateways. Is there any way to avoid this or to achieve the same result in a different way? Best Regards

Hi, I'm experimenting "onsend_route" with "onsend_route_reply=yes" to improve my logs.

The documentation seems to indicate that this route will execute only if "the received reply is sent out". -as I'm forking, the final 6xx answer is not "forwarded" immediatly... and I guess this is the reason it doesn't show.

If I can't use two tables, is it possible to read them from a Mysql View? I want to be able to have a Gateway belonging to more than one Gateway Set. By doing so, in the table, the gateway will be repeated but with different groups. How will the probing work in this scenario? Will the Gateway be probed multiple times? Thanks for your help. Cheers
