Releasing Kamailio v5.3.0

by Daniel-Constantin Mierla

Hello, if there are no known major issues that need longer time to take care of them, in my opinion we could consider releasing the next major version 5.3.0 next week, for me Thursday, October 10 seems to work the best, still allowing a bit more than one week for testing. Any other suggestions?

catching tls errors

by Juha Heinanen

Sometimes I see in syslog errors like this: Oct 15 16:44:57 salmon /usr/bin/sip-proxy[2064]: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1417C086:SSL routines:tls_process_client_certificate:certificate verify failed Is it possible somehow to catch the error in config file, for example, to figure out from which IP address the connection attempt came from? -- Juha

Kamailio weighted dispatch problems

by Jasen Hall

I am trying to change our request dispatching from round-robin to a weight-based method (ds_select_dst() algorithm 9 vs. algorithm 4) and am having a hard time getting an asymmetrical dispatch pattern enabled. In testing, I'm dispatching to two Ringswitch servers and trying to send three times the traffic to one instance. My destinations list file previously set both endpoints in the same group and simply provided the SIP URI for each. My new list file adds the attribute `weight` to each endpoint and looks like this: >1 sip:10.0.0.1:5060 weight=3 >1 sip:10.0.0.2:5060 weight=1 However, when I throw a couple thousand calls at Kamailio, I always end up with an almost perfect split of calls to both ringswitches. Regardless of the weights I choose, I never see variation in the dispatched load. Does anyone have experience with this issue and have some guidance? Thanks in advance. -- Jasen Hall | Invoca *Site Reliability Engineer* www.invoca.com [image: See the list] <https://invoca.sigstr.net/uc/5cba111d3527a200469b9afd>

SSL Offloading with AWS ELB or Google GSLB and Kamailio

by Joel Serrano

Hi everyone, I was giving a try to setup Kamailio with a Cloud TCP load balancer in front, taking advantage of the newly added proxy protocol compatibility and my initial tests went very well. Flow: client -> (tcp) -> load balancer -> (tcp) -> Kamailio TCP socket I then did another quick test and enabled TLS, also with good results: Flow: client -> (tls) -> load balancer -> (tls) -> Kamailio TLS socket So far so good, proxy protocol works as expected. I wanted to go one step further and see if I could somehow offload SSL operations at the load balancer level, and leave kamailio handling plain tcp. Flow: client -> (tls) -> load balancer -> (tcp) -> Kamailio TCP socket This partially worked, and before I start digging into what I have to do to get it completely working, I'd like to know if anyone already has a similar setup, or even if Kamailio is able to handle such a scenario, the reason I'm asking is because of the headers, etc. In this last scenario, I receive in a TCP socket, a request with TLS headers all over the place.. INVITE sip:14a84f2016944eb0854ef0e9b71bfa10@app.mydomain.com:60655 SIP/2.0 Via: SIP/2.0/TLS 192.168.1.16:60717;branch=z9hG4bK.KmUpamn5P;rport From: ... To: ... CSeq: 21 INVITE Call-ID: -j1QSnam9o Max-Forwards: 70 Route: <sip:sbc-test2.mydomain.com:443;lr> <http://sbc-test2.sbx.gii.me:443;lr>/> Supported: replaces, outbound Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, MESSAGE, SUBSCRIBE, INFO, UPDATE Content-Type: application/sdp Content-Length: 436 Contact: <sip:linphone@A.B.C.D:60717;transport=tls>;+sip.instance="<urn:uuid:fabcb441-a348-49a7-948d-72448d6840eb>" I then forward this request via UDP to subsequent proxies for further processing, on the replies, my payload information back to the client should be TLS, although sent via a TCP socket.. Is this something that will not work by design? Is there any hack I can take advantage of? The goal would be for Kamailio to handle TLS headers via TCP socket, as the client expects TLS information, but the actual traffic should go in plan TCP, and the load balancer will take care of re-encrypting before replying to the client. Any ideas/suggestions/comments? I hope this email is understandable, I find it complicated to detail the exact problem, feel free to ask any questions if you don't understand anything. Thanks, Joel.
