Install Kamailio 5.3
by Daniel Oliveira Hilário 30 Aug '23

30 Aug '23

Hi people, I installed Kamailio 5.3 on Ubuntu Server 22 LTS, but I am not able to resolve several PHP errors that occur when I try to open the website http://localhost/siremis/. Which Linux distro and version is best suited for installation? Is Kamailio version 5.3 operational or is it better to use version 4.4? Att., Daniel Hilário INFRACOM/UFRGS 51 3308 4801

Kamailio stops processing UDP on one interface
by Ihor Olkhovskyi 30 Aug '23

30 Aug '23

Hello, I've faced a bit strange issue, but a bit of preface. I have Kamailio as a proxy (TLS/WS <-> UDP) and second Kamailio as a presence server. At some point presence server accepts around 5K PUBLISH within 1 minute and sending around the same amount of NOTIFY to proxy Kamailio. Proxy is "transforming" protocol to TLS, but at sime point I'm starting to get these type of errors tm [../../core/forward.h:292]: msg_send_buffer(): tcp_send failed tm [t_fwd.c:1588]: t_send_branch(): sending request on branch 0 failed <script>: [RELAY] Relay to <sip:X.X.X.X:51571;transport=tls> failed! tm [../../core/forward.h:292]: msg_send_buffer(): tcp_send failed tm [t_fwd.c:1588]: t_send_branch(): sending request on branch 0 failed Some of those messages are 100% valid as client can go away or so. Some are not, cause I'm sure client is alive and connected. But the problem comes later. At some moment proxy Kamailio just stops accept UDP traffic on this interface (where it also accepts all NOTIFY's), at the start of the "stopping accepting" Kamailio sends OPTIONS via DISPATCHER but not able to receive 200 OK. Over TLS on the same interface all is ok. On other (loopback) interface UDP is being processed fine, so I don't suspert some limit on open files here. Only restart of Kamailio proxy process helps in this case. I've tuned net.core.rmem_max and net.core.rmem_default to 25 Mb, so in theory buffer should not be the case. Is there some internal "interface buffer" in Kamailio that is not freed upon failure send or maybe I've missed somethig?

How to forward 480
by Anthony Blandin 29 Aug '23

29 Aug '23

Hello, I have a Kamailio SBC connected to another foreign SBC and to a media server. In case of non response, Kamailio SBC receives a 480 Temporarily not available from the foreign SBC and I need to forward this 480 to my media server but I don't see how to do that. The 480 arrives in the onreply_route. If I use then a failure_route, it resends the initial INVITE and not the 480. Is there a way to do that? Thanks for your help. Anthony Blandin

Or, if you are good at Google search, I believe you can definitely find more ways to play the big dildo. All in all, huge dildos are the best sex toy for singles. For single women, it’s vaginal masturbation. For single men, it’s anal sex. https://www.hugedildo.com/

hi, i have open around ~8000 rtp ports for around ~200calls (in peak) with this statistic (current data, not from peak) rtpengine_closed_sessions_total{reason="rejected"} 0 rtpengine_closed_sessions_total{reason="timeout"} 237405 rtpengine_closed_sessions_total{reason="silent_timeout"} 103 rtpengine_closed_sessions_total{reason="final_timeout"} 0 rtpengine_closed_sessions_total{reason="offer_timeout"} 0 rtpengine_closed_sessions_total{reason="terminated"} 0 rtpengine_request_seconds_total{proxy="127.0.0.1",request="offer"} 539.270967 rtpengine_request_seconds_total{proxy="127.0.0.1",request="answer"} 367.237641 rtpengine_request_seconds_total{proxy="127.0.0.1",request="delete"} 0.000000 is it normal? (large number of timeouts, "zero" terminated) or i have missing rtpengine_manage (rtpengine_delete) somewhere? (os rocky 9.2, kamailio 5.6.4, rtpengine 11.3.1) thanks Marek
