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

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

[tracker] Task opened: Via parser does not accept any token as transport

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Iñaki Baz Castillo (ibc) Attached to Project - sip-router Summary - Via parser does not accept any token as transport Task Type - Bug Report Category - Core Status - Assigned Assigned To - Andrei Pelinescu-Onciul Operating System - All Severity - Low Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - Hi, sip-router Via parser is not RFC compliant as it does not accept any token in the transport (even if this does NOT occur in the top Via). A real example: kamailio receives a REGISTER like this (removing other headers): REGISTER sip:domain,org SIP/2.0 Via: SIP/2.0/UDP 1.2.3.4:9090;branch=z9hG4bK3afb3d8e9ea4c4259f9d;rport Via: SIP/2.0/WS 1.2.3.4:36638;branch=z9hG4bK5089;received=9.9.9.9;rport=36638 And it fails parsing so also processing the request: ERROR: <core> [parser/parse_via.c:1677]: ERROR: parse_via: bad char <W> on state 122 ERROR: <core> [parser/parse_via.c:2366]: ERROR: parse_via on: <SIP/2.0/UDP 1.2.3.4:9090;branch=z9hG4bK3afb3d8e9ea4c4259f9d;rport [...]> ERROR: <core> [parser/parse_via.c:2370]: ERROR: parse_via parse error, parsed so far:<SIP/2.0/> ERROR: <core> [parser/msg_parser.c:139]: ERROR: get_hdr_field: bad via INFO: <core> [parser/msg_parser.c:353]: ERROR: bad header field [Via: SIP/2.0/WS 1.2.] Please, make it possible for the Via transport to contain an unknown token, at least when it does NOT occur in the top Via header. Why should Kamailio care about the second Via transport field? Thanks a lot.
