New user checking on SIP proxying use case
by Nick Hurlburt 22 Jul '21

22 Jul '21

Hello all, My name is Nick Hurlburt, and work with a nonprofit tech organization that provides a software platform for child helplines around the world. I am a new user to Kamailio, and I'm interested in figuring out if my use case is appropriate, getting some tips on how to go about it, and possibly enlisting some expert help. Our service is built on top of Twilio, but we are working in some countries where Twilio doesn't have phone numbers. So in those areas, we are working with local telecoms on ways to integrate using a SIP connection. In one particular example, the telecom company can send SIP INVITEs but can only address them to a static IP. However, Twilio needs to receive the invite addressed to a fully-qualified domain name (eg, example-setup.sip.twilio.com). The idea arose to use Kamailio as a proxy to accept the static IP-addressed request and then rewrite the request to pass it along to a domain name. Then once the connection is established between the two endpoints, the media can flow directly between them. I have a software engineering background but still coming up to speed when it comes to VoIP technology. I'd be interested in: - does this sound like a good use case for Kamailio? - is there any specific documentation you could point me to for this use case? (I have been looking at the Kamailio documentation, but a quick pointer could save a lot of time in digging through it) - if anyone from the community would be open to helping us develop a prototype/proof-of-concept instance of this, especially if you're open to contributing to a nonprofit on a volunteer or discounted rate, I'd love to talk more Thank you, Nick

Kamailio/rtpengine not populating mos avp stats?
by Anthony Joseph Messina 22 Jul '21

22 Jul '21

I'm using Kamailio compiled from the current 5.5 tip (1f9f6fff6e), and rtpengine compiled from the current master (6e160da4). While rtpengine is working quite well, within the past month or so, I've noticed that Kamailio isn't populating the mos* related AVPs. I see continued upstream rtpengine work stream handling, etc. -- should I wait or try to debug? Thanks -A -- Anthony - https://messinet.com CCED 8BFB 88D9 18F6 9F68 93DC 45C4 A8CE A64E 88E3

How to get Stir/Shaken certificates
by ryan embgrets 22 Jul '21

22 Jul '21

Greetings. Does someone know where one can get stir/shaken certificates? Are they same as letsencrypt or do I need to obtain them from some other authority. If someone could provide me with a link to that authority it will be very helpful. Thanks again for your help and time. Ryan

Question about MS Teams integration
by Володимир Іванець 22 Jul '21

22 Jul '21

Hello all! Sorry, this is not a direct Kamailio question. I would like to ask for some help from those who already did this. I'm trying to integrate my testKamailio installation with MS Teams. I added the "mydomain.com" to the Domains section (I kept the " mydomain.onmicrosoft.com"). When I tried to create SBC with a " kamailio-dev2.mydomain.com" FQDN I got this error message: We* can't use the "kamailio-dev2.mydomain.com <http://kamailio-dev2.mydomain.com>" domain as it hasn't be set up in the organization. Try again. If you continue to have problems, contact Microsoft customer support.* There were no issues creating a dummy SBC with a " kamailio-dev2.mydomain.onmicrosoft.com" FQDN. Does anyone know how to set up a domain in the organization from MS perspective? Thank you very much! Regards, Volodymyr Ivanets.

serial forking kamailio - twilio
by Filippo Graziola 21 Jul '21

21 Jul '21

Hi all, I have a question for my kamailio configuration which works like this: - INVITE arrives to kamailio - HTTP async request to API endpoint - Resume, use of rtjson module for parallel forking and loop to kamailio itself - One of the invite is "transformed" in serial forking with rtjson module and it is sent with a delay to TWILIO SIP Domain (landline/mobile phone numbers) Twilio is giving me some troubles because it answers with a 200 OK but the call it is still in establishing/ringing on the "landline" side and as expected when reaching the timeout (no answer from phone number on TWILIO side) kamailio is receiving a BYE. Now the question, how to handle next number to call through Twilio? I was thinking of using rtjson_next_route() when handling the in-dialog BYE but as it is not a failure route so it does not work, or I'm doing it wrong. Thanks in advance for any help/hint. Filippo

Re: [SR-Users] Kamailio KeepAlived HA acc_cdrs table record
by Henning Westerholt 20 Jul '21

20 Jul '21

Hello, I have not tested it, but the dialog database will probably only help in a restart scenario with regarding to dialogs, at least with a standard cfg. Regarding the example below, this would mean starting the primary Kamailio again, then the cdrs should be generated during the hangup from the primary. You can test also to restart the secondary Kamailio, it should then also read the dialogs from the replicated table and generate cdrs at hangup.

Kamailio python_exec getting randomly TypeError
by Voip support 19 Jul '21

19 Jul '21

Dear Kamailio users, I am trying to use a python script using the module app_python3 to do some billing calculations. The only argument i want to pass to the python script is duration which i calculate in event_route[dialog:start] { $dlg_var('call_start') = $TS; event_route[dialog:end] { $var('v_duration') = $TS - $dlg_var('call_start'); So my $var('v_duration') has the duration of the call in seconds. Then i execute from my kamailio.cfg: python_exec("calculateCost","$var('v_duration')"); The script works randomly - sometimes all is good and sometimes it throw error : app_python3 [python_support.c:156]: python_handle_exception(): apy_exec: calculateCost(4): Unhandled exception in the Python code: TypeError: an integer is required (got type NoneType) The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/etc/kamailio/kamailio-python.py", line 282, in calculateCost duration = int(duration) It looks like the kamailio log show calculateCost(4) so argument 4 is passed to python function but once it executes it appear like there is no string/integer but NoneType argument. I cannot figure this out why this randomly happens - maybe it's an app_python3 module issue? Looking to hear back from you! BR, Tom

17 Jul '21

Hello, Does anybody know how i could change white filter in siprelpy in sems? In Kamailio, I got "200 OK" from UE, then add a new header (SBC: mt-reply) and send it to sems server. The sems server remove it: [#7f410fbfb700/4560] [inplaceHeaderFilter, HeaderFilter.cpp:226] DEBUG: erasing header 'sbc' by whitelist I really don't want to remove it. Actually if I knew how i active profile for sip replying in sems, I would be able to solve this. Thanks with regards. -- --Mojtaba Esfandiari.S
