Kamailio IMS - VM
by Bruno Cruz 17 Nov '15

17 Nov '15

Hello everyone, My name is Bruno, I'm a student from Portugal studying IMS at the moment. I've been following tutorials online, trying to get Kamailio to work as an IMS core - I'm pretty much a newbie in this field. Unfortunantly I've been getting several errors and I can't seem to properly configure everything. I was wondering if there is a All-in-One VM that can be downloaded, with Kamailio ready to be used as an IMS core? Thanks in advance. Best regards, Bruno C.

I try subst_hf with regexp, subst and simply remove Contact, all this does not work. What i am doing wrong? -- С уважением Зуев Михаил

pv_printf buffer for spec value
by Sven Neuhaus 05 Nov '15

05 Nov '15

Hello, I'm getting these errors since the last couple of changes I made to the Kamailio 4.3.x configuration: ERROR: <core> [pvapi.c:1361]: pv_printf(): no more space for spec value ERROR: <core> [pvapi.c:1370]: pv_printf(): buffer overflow -- increase the buffer size... I'm not even using pv_printf() so this error is a bit surprising. The first thing I tried was increasing the buffer from its default size of 1024 to 4096 (pv_buffer_size=4096) but the error messages persist. What other functions use this buffer? Regards, -Sven Neuhaus

listening on multiple port
by Thibault Gueslin 04 Nov '15

04 Nov '15

I would like to set up kamailio in order to listen to multiple port. I have set : port=5060 port=5228 But it always listen on the port indicated on last line: Listening on udp: 127.0.0.1:5228 udp: x.x.x.x:5228 tcp: 127.0.0.1:5228 tcp: x.x.x.x:5228 Aliases: I don't have any "listen" in my config file. Is it supposed to work like that ?

On the "General" tab, please look for the "Track" option and choose "Real-Time devroom". https://penta.fosdem.org/submission/FOSDEM16/ Other dev-rooms: some speakers may find their topic is in the scope of more than one dev-room. It is permitted to apply to more than one dev-room but please be kind enough to tell us if you do this. You can find the full list of dev-rooms at https://www.fosdem.org/2016/schedule/tracks/ Lightning talks: deadline 27 November The lightning talks are an excellent opportunity to introduce a wider audience to your project. Given that dev-rooms are becoming increasingly busy, all speakers are encouraged to consider applying for a lightning talk as well as a slot in the dev-room. On the "General" tab, please look for the "Track" option and choose "Lightning Talks". https://fosdem.org/submit First-time speaking? -------------------- FOSDEM dev-rooms are a welcoming environment for people who have never given a talk before. Please feel free to contact the dev-room administrators personally if you would like to ask any questions about it. Submission guidelines --------------------- The Pentabarf system will ask for many of the essential details. Please remember to re-use your account from previous years if you have one. In the "Submission notes", please tell us about: - the purpose of your talk - any other talk applications (dev-rooms, lightning talks, main track) - availability constraints and special needs You can use HTML in your bio, abstract and description. If you maintain a blog, please consider providing us with the URL of a feed with posts tagged for your RTC-related work. We will be looking for relevance to the conference and dev-room themes, presentations aimed at developers of free and open source software about RTC-related topics. Please feel free to suggest a duration between 20 minutes and 55 minutes but note that the final decision on talk durations will be made by the dev-room administrators. As the two previous dev-rooms have been combined into one, we may decide to give shorter slots than in previous years so that more speakers can participate. Please note FOSDEM aims to record and live-stream all talks. The CC-BY license is used. For any questions, please join the FSFE-sponsored Free RTC mailing list: https://lists.fsfe.org/mailman/listinfo/free-rtc Volunteers needed ================= To make the dev-room and lounge run successfully, we are looking for volunteers: - FOSDEM provides video recording equipment and live streaming, volunteers are needed to assist in this - organizing one or more restaurant bookings (dependending upon number of participants) for the evening of Saturday, 30 January - participation in the Real-Time lounge - helping attract sponsorship funds for the dev-room to pay for the Saturday night dinner and any other expenses - circulating this Call for Participation to other mailing lists FOSDEM is made possible by volunteers and if you have time to contribute, please feel free to get involved through https://volunteers.fosdem.org/ Related events - XMPP and RTC summits ===================================== The XMPP Standards Foundation (XSF) has traditionally held a summit in the days before FOSDEM. There is discussion about a similar summit taking place on 28 and 29 January 2016 http://wiki.xmpp.org/web/Summit_19 - please join the mailing list for details: http://mail.jabber.org/mailman/listinfo/summit We are also considering a more general RTC or telephony summit, potentially on 29 January.

Huge TLS performance regression migrating from 3.3.7 to 4.2.6
by Tristan Mahé 03 Nov '15

03 Nov '15

Hi List, I've been reaching a strange thing lately, trying to upgrade to kamailio 4.2.6 ( identical config ): - 35% loss of performance on TLS connections ( Sipp REGISTER scenario, easily reproduced ). - more TCP workers needed to ease the TCP queues ( 32 workers on 3.3.7, at least 64 are needed on 4.2.6 to avoid "queue full" messages in logs ). - kamailio 4.2.6 intermittent processing of requests ( Kamailio stops accepting new tcp connections, then resume a bit later, then stops again,... ) => starts happening when Kamailio is treating more than 20k tcp connections, with between 500-1k req/s. During those periods, trying to connect to kamailio with an openssl s_client -connect will end up in a timeout or with a long delay before the certificate is received ( 03 CONNECTED ). - kamailio 4.2.6 dropping connections, kamailio 3.3.7 keeping those connections: after a while, the number of active connections starts to decrease on kam4, on kam3 it stays constant. I was wondering if I was alone in this situation or if someone else is impacted, has some advices ? It does not seem to be a config issue, as it is the same that was deployed with both versions.

What files and where should I update? Should I run kamdbctl? Thanks, Nir
