10 Years SER - Awards
by Daniel-Constantin Mierla 05 Sep '11

05 Sep '11

Hello, a surprise part of 10 Years SER Conference was granting *special* awards to the people attending the event that had a major contribution in the management and development of SER/Kamailio to date. Most of them are well known in the community, but not all of them. Hope you like them, it proved to be a very entertaining moment. Here is the pdf with the awards: * http://asipto.com/u/48 The plan is to extend it with the other people in our community as ideas with award titles pop up. Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Oct 10-13, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

10 Years SER - Follow UP
by Daniel-Constantin Mierla 05 Sep '11

05 Sep '11

Hello, first I want to thank to all participants at 10 Years SER event in Berlin last Friday. We spent great time, at least I did! We accepted 50 visiting participants to match the maximum capacity of the conference room, being full booked about 2 weeks before. Just few people didn't show up and didn't inform us at all in advance, which was a pity over all since several persons that registered later were not accepted, thus some of them could have attended. Folks at Fokus working with SER/Kamailio joined us and we had probably one of the very few occasions so far to get so dense knowledge of SIP/VoIP in the same place, making a day of interesting presentations and open discussions. Accompanied by nice weather in Berlin, the evening at Playa Paradiso on river Spree offered a great place for continuing the technical and mufti-cultural debates (I could count attendees from about 15 countries (including Brazil!)). Many thanks again to our sponsors for free drinks and food at this event: Sipgate (http://www.sipgate.de), Amooma (http://www.amooma.de), NG-Voice (http://www.ng-voice.com), Asipto (http://www.asipto.com), Frafos (http://www.frafos.com) and Fokus Institute (http://www.fokus.fraunhofer.de). I will upload the presentations soon and send an update here -- there were 15 talks, covering from technical concepts to business matters and open source philosophy. Therefore if you were a speaker and see this message, please send the pdf slides to me. Do not forget, you can join the next party for this celebration this week in Vienna, details at: * http://sip-router.org/10-years-ser-vienna/ Meanwhile, be sure you start/continue testing the upcoming release v3.2.0, we have to be sure it is stable to release it and start a new development cycle in the near future, to be able to present new features at the 11th celebration :-) . Here is a step by step guide to pull the code from GIT and install: * http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-devel-from-git Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Oct 10-13, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

tls + tcp problems
by MÉSZÁROS Mihály 05 Sep '11

05 Sep '11

Hi, I am experiencing two problem: First: I am experiencing that tls read buffer overflow, if i use default value of tcp_rd_buf_size If i doubled the size of read buffer and i use tcp_rd_buf_size=8192 then the problem seems to be solved. Second: I am experiencing that TLS connection is dropped by sip proxy very frequently! And i think the tcp connection shouldn't dropped! So my guess is that TLS communication is not restarting the timeout counters! So in every 2 minutes the sip-router is restarting the TCP connection with tcp RST. like this: Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:4304]: tcp_main: entering timer for 0xac537c74 (ticks=446299809, ti meout=446299809 (0 s), wr_timeout=0 (240541717 s)), write queue: 0 bytes Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:4346]: tcp_main: timeout for 0xac537c74 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [io_wait.h:617]: DBG: io_watch_del (0x824cf80, 48, -1, 0x10) fd_no=41 called Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: tls [tls_server.c:597]: Closing SSL connection 0xac4a0374 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [ip_addr.c:247]: tcpconn_new: new tcp connection: 10.10.10.10 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:1081]: tcpconn_new: on port 36142, type 3 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:1382]: tcpconn_add: hashes: 2473:3781:3367, 5 This second problem is not solved and very urgent for me. Any help suggestion is highly appreciated! Thanks, Misi

Carrier module for kamailio
by Mino Haluz 05 Sep '11

05 Sep '11

Hi, I need a module which could allow me to send traffic to various carriers and it has to support some important features. So some basic ones: - possibility to re-route the call in case the original route fails - peak/offpeak conditions (time-based) - route traffic according to prefix I found LCR and carrierroute module, but it does not have peak/offpeak feature. Correct me if I am wrong..

Kamailio + rtpproxy talking to multiple carrier gateways - some via Firewall/NAT
by Sarat C. Vemuri 03 Sep '11

03 Sep '11

We are trying to configure Kamailio (3.1.x) as a "boarder proxy" where it acts as the front for various carrier gateways so that internal UACs and UASs are unaware of the carrier gateways. Let me try to present a clear picture of our setup. 1. Kamailio has several NICs (physical or vlan). Each on a different subnet. One subnet is internal/has routes for internal. Other subnets are private connections to carriers or a route to public Internet. 2. All of these subnets are non-routable from Internet. In addition , the carrier private connections are not routable internally. 3. Connection to public internet is via a FW/NAT (one-to-one NAT), which maps to one of the interfaces. 4. All internal UAC/UAS connect on the internal subnet. 5. We are using RTPProxy (at least one instance per carrier) to relay media between internal and carrier subnets We are able to make this setup up work great except for one scenario. One of the carriers is only reachable via public Internet. Due to security requirements, our Kamailio cannot have a public IP address and must use FW/NAT. I guess this scenario is "Proxy behind NAT" and not really encouraged. But I would like to see if there is a way to make this work. We cannot use the "advertised_address" since it changes the IP for every "route". We were able to get this mostly working by doing the following 1. mhomed=1 2. Small patch in the rtpproxy module so that force_rtp_proxy actually uses the IP address passed (public IP). 3. Using request_route_preset("publicIP") The above "mostly" works. By that I mean, the INVITE transaction is properly passed between internal UAS and carrier SBC and the call is setup. However, further transactions (BYE/re-INVITE) etc do not work properly. So, far-end hangups are not working etc. I've searched various archives of this and other SER lists looking to see if anyone was able to get this scenario working, but couldn't find a definitive answer. Most of them point to using "advertised_address". So, and ideas on how to make "Proxy behind NAT" work without using advertised_address? Am I wasting my time? Thanks in advance for any help you can offer. SV.

10 years of SER - statistics
by Daniel-Constantin Mierla 31 Aug '11

31 Aug '11

Hello, it is now one month till the 10 years SER event in Berlin. I am thinking to collect few statistics about usage of SER-based code at this moment (SER, OpenSER, Kamailio, OpenIMSCore ...) and present them during the conference and publish on the web. Everything is going to be like a combined report, not individual listing. Therefore, if you want to participate, your name or company won't be mentioned. Here are the stats I thought of: - type of usage: production, evaluation (testing), research - number of subscribers (phone lines) - percentage of phones behind NAT - number of calls per month - number of call minutes per month I am not looking for exact numbers, but rough estimation (e.g., about 10 000 phone lines, ...). Of course, some of the metrics don't apply always (e.g., if you do termination routed through SIP server, you don't have subscribers, but just calls traffic). Those doing deployments, can make one summary of statistics for all instances. You may send other statistics you think they worth publishing. Again, this is voluntary, naming is not required. I hope only those giving real number will write back -- I will try anyhow to figure out if someone is just dumping fantasy numbers. If privacy is really a big concern, from case to case, everything can be done under NDA.

Celebrating 10 years SER SIP Router in Vienna: 8th September 2011
by Klaus Darilion 31 Aug '11

31 Aug '11

Hi! If you haven't noticed yet, SER (the mother of the SIP proxy projects Openser, Kamailio, sip-router, opensips, ....) is celebrating their 10th year. There will be a main event happening in Berlin (http://sip-router.org/10-years-ser/). For those who can not travel to this event, there will be some smaller events around the world. In Vienna, this will happen on the 8th September at 7pm in the evening, organized by Andreas Granig and myself. We do not plan to have a big event with speaker, it is just an informal come together to meet with other SER-interested[1] guys, having some techie talks, maybe getting some business contacts and drinking some beers. Drinks will be sponsored by http://www.ipcom.at/ and http://www.sipwise.com/. The event will happen in the city center of Vienna. The location is not fixed yet, it depends on how many people are going to attend. Thus, please let us know if you going to attend (send us a short e-mail) and spread this e-mail to interested people you know. Cheers Andreas and Klaus [1] User's of all SER-flavors are welcome
