crash when sending reply
by Juha Heinanen 02 Jul '21

02 Jul '21

Kamailio 5.5 crashed when sending reply (bt full below). Before the crash there had been several mysql related error messages ("Lost connection to MySQL server during query" and "Too many connections") in syslog when async worker tried to insert accounting data. So perhaps this core dump has something to do with that. -- Juha Reading symbols from /usr/bin/sip-proxy...done.

UAC_AUTH with RTPEngine NAT
by Paul Smith 02 Jul '21

02 Jul '21

Hi, [Note I posted this yesterday from the wrong email address.] I am struggling to see why my SDP is not being set correctly on the INVITE to my supplier with Proxy-Authentication when I use uac_auth(). The initial INVITE to my supplier has correct SDP set by rtpengine_manage. Then supplier replies with a 407. My failure route correctly handles the Auth, and also calls NATMANAGE again... but this time the SDP is unchanged and the private IP and original media information from the original device is relayed to my supplier. kamailio.cfg isbased on the default config. Running kamailio 5.4.6 and using example from uac module for uac_auth. My failure route calls NATMANAGE. Is there anything special about uac_auth? Do I need some extra magic to apply the message body changes after I have run rtpengine_manage(). I can see that the NATMANAGEr test for nat_uac_test("8") is true, and rtpengine_manage() s being called. But the outgoing SDP is not changed. Thanks for any hints! Paul ==================== Extract of kamailio.cfg failure_route[TRUNKAUTH] { if (t_is_canceled()) { exit; } route(NATMANAGE); xlog("L_INFO","In failure route, just finshed NATMANAGE and now body is $mb"); if(t_check_status("401|407")) { # $avp(auser) = "test"; # $avp(apass) = "test"; # $avp(apass) = "36d0a02793542b4961e8348347236dbf"; if (uac_auth()) { t_relay(); } exit; } }

Kamailio BSD license
by stevecarellccie＠yahoo.com 01 Jul '21

01 Jul '21

Hello, I am trying to use Kamailio in our application which would be deployed in certain environment in addition to a cloud infrastructure. As I understand it, parts of the Kamailio code are covered under the BSD license - are you able to share what those are? I am trying to determine if Kamailio can be used in a customer environment or should it be strictly restricted to cloud environments due to the GPL v2 licenses Thanks,Steve

install stirshaken module by apt at Debian 10

Hi, I know that it's possible to compile manually but what about apt method to install stirshaken module? I am checking the list of modules using: apt search kamailio But... Nothing looks like stirshaken. Thus, only several modules available and for others we should compile manually ? Please advise Thanks

Websocket In-dialoge SIP routing failed post network loss due to aliases
by Shahid Hussain 30 Jun '21

30 Jun '21

Hi, Websocket module documentation has a code reference to use aliases for SIP routing. However, aliases will not work in the following setup and situation. 1. Kamailio is configured with active and standby node 2. Ping is implemented from webclient and kamailio responds with pong. 3. Two clients ClinetA and ClientB registered themselves to Kamailio. 4. After SIP negotiation (INVITE-200OK) each client learnt about below aliases. Alias of ClientA: alias=172.27.6.98~58336 Alias of ClientB: alias=172.27.6.98~58342 So normally if ClientB wants to send SIP message to ClientA, SIP URI from ClientB looks like below ACK sip:v9d0gtl6@q0lrdlj63pik.invalid;alias=172.27.6.98~58336~5;transport=ws SIP/2.0 4. Call is in a connected state. Following is the issue. i. Switchover (or network lost or reboot) at Kamailio happened ii. Due to ping pong both the clients detected network loss individually and re-registered themselves. iii. Aliases of both the clients got changed. New Alias of ClientA: alias=172.27.6.98~ 58346 New Alias of ClientB: alias=172.27.6.98~ 58348 iv. But ClientB doesn’t know that ClientA also re-registered and ClientA’s alias got changed and vice-versa v. Because of this ClientB still sends BYE with Initial alias BYE sip:v9d0gtl6@q0lrdlj63pik.invalid;alias=172.27.6.98~58336~5;transport=ws SIP/2.0 Would like to know what is the recommended solution for this problem using alias or is it a limitation of using alias? Thanks & Regards, Shahid

You are creating a transport bridge (UDP <-> WSS i.e. stateless transport <-> stateful transport) as well media bridge (RTP <-> SRTP), so it is going to be tricky. I strongly discourage it since things get messy for sequential requests. But you can try the following, Here are some PATH module parameters and functions, you will need to setup. 1. You will need to enable "use_received" parameter to ensure connection tracking. 2. It seems you may have enabled "received_format", so you make sure you do NAT detection and use "handle_ruri_alias" for initial requests. 3. You must also enabled "enable_r2", but with caution, since both ends (i.e. UAC and UAS) can be using same kamailio (proxy) socket for in/out. 4. Make sure to use "add_path_received" instead of "add_path". 5. If using OUTBOUND module then make sure it is loaded BEFORE the PATH module.

Kamailio + RTPEngine - Destinations Behind NAT
by Edward Romanenco 29 Jun '21

29 Jun '21

Hi everyone, I'm using Kamailio (Ver 5.5.1, Public IP X.X.X.11, Private IP 172.18.0.20) + RTPEngine (Ver 9.4.1.1, Public IP X.X.X.7, Private IP 172.18.0.50) alongside Freeswitch (Private IP 172.18.0.40) in my backend and delivering calls to a mobile application (call flow is Freeswitch -> Kamailio + RTPEngine -> Applicaiton). While calls made to NATted destination generally works fine - from time to time, we've experiencing one-sided audio due to the rtpengine sending the media stream to the remote end's private IP instead of his public one. For instance, in the attached logs - media was sent towards 192.168.1.93 instead of 79.179.1.2, which is the expected destination. Problem appears almost randomly; I can make 20 fine calls in a row for the same destination until experiencing it, and I didn't find any difference as it comes to the SIP invite exchange between the two. Has anyone ever experienced the same behavior and can share some general instructions on how to troubleshoot it? Relevant Kamailio config section is attached.
