htable ::size has wrong value
by Juha Heinanen 24 May '11

24 May '11

i have entries in htable with key name lpi::20033::prefix: # sip-proxy_ctl mi sht_dump htable | egrep 20033 lpi::20033::prefix[0]:: +3583796294 lpi::20033::prefix[1]:: +35837824030 lpi::20033::prefix::size:: 1 as you see in above, size of that key name is 1 although there clearly is two entries in the table with that key name. according to readme ::size is number of items: 3.7. array_size_suffix (str) The suffix to be added to store the number of items in an array. i verified with another key name where there was only one prefix, and then ::size was again 1. so sometimes ::size is correct and sometimes incorrect. this looks like a serious bug to me. any comments? -- juha

Re: [SR-Users] app_lua in kamailio

Hello, please do not write direct private emails for questions about kamailio, use public mailing list sr-users(a)lists.sip-router.org (cc-ed) -- private emails are ignored, after the first notification. exit is not a function exported by a module, it is implemented in core. On the other hand, you try to stop the kamailio cfg interpreter when lua interpreter is executing the Lua script, so it won't work straightforward. Set a variable in kamailio from Lua, then check it after executing the lua script to decide to further exit or not.

SEMS 1.4.0 release
by Stefan Sayer 24 May '11

24 May '11

We are happy to announce the availability of the SIP Express Media Server version 1.4.0. SEMS is a high performance media and application server for SIP based VoIP networks. This release features a powerful Session Border Controller (SBC) module. From completely transparent B2BUA to customized URI/From/To, strictly filtered (messages, headers, codecs) with RTP anchoring, Session Timer enforcement, prepaid and call timer, the SBC facilitates interconnect and core routing in a simple and secure way. Thanks to the new multihoming support, SEMS can now be employed at the border of the networks. This addition also allows to overcome the bottleneck of one NIC - giving the possibility to fully exploit SEMS' great performance. In the app development area, the DSM language has matured to become a viable candidate also for implementing complex application logic, thanks to language constructs like for, if and functions. SEMS can be downloaded in source from its ftp site at: ftp.iptel.org/pub/sems/1.4/1.4.0/ Packages for debian/ubuntu should appear shortly on the OBS page: https://build.opensuse.org/project/show?project=home:team-sems Contributors to this release: Stefan Sayer, Raphael Coeffic, Bogdan Pintea, Matthew Williams, Peter Lemenkov, Anton Zagorskiy, Robert Szokovacs, Jon Bonilla, Thomas Gelf, Erik Dekkers, Tobias Lindgren, David J Many thanks to the companies sponsoring SEMS development, especially FRAFOS GmbH and TelTech Systems Inc.

newbie INVITE routing logic help
by Skyler 24 May '11

24 May '11

Hi all, Need some newbie advice on how to write INVITE routing for my scenario. I currently have kamailio+asterisk-realtime integration working in the following way: Outbound calls: USER-A -> Kamailio(3.1.3) -> Asterisk(1.6.2.18) ;if dest local then Asterisk(1.6.2.18) -> Kamailio(3.1.3) -> USER-B ;if dest not local then Asterisk(1.6.2.18) -> SIP/PSTN This works, though I'd prefer to use Kamailio + LCR and gateway failover as Asterisk doesn't do this well. Here's what I want to do: (for now, small steps) Outbound Calls: USER-A -> Kamailio(3.1.3) -> Asterisk(1.6.2.18) ;if dest local then Asterisk(1.6.2.18) -> Kamailio(3.1.3) -> USER-B ;if dest not local then Asterisk(1.6.2.18) -> Kamailio(3.1.3)+(lcr) -> SIP/PSTN I know I have to set kamailio as a GW in asterisk instead of the PSTN GW's and add the PSTN GW's to kamailio instead, though I'm at a loss as to how to write the routing logic so that kamailio sends calls from asterisk to PSTN. route[LOCATION] { ...non-INVITE check ends here... if(route(FROMASTERISK)) { # coming from Asterisk --- Does this mean check kamailio local users first before continuing? if (!lookup("location")) { switch ($rc) { case -1: case -3: t_newtran(); t_reply("404", "Not Found"); exit; case -2: sl_send_reply("405", "Method Not Allowed"); exit; } } ## -- If match 11 digits and starts with '1' or if match 10 digits and starts with [2-9] if($rU=~"^(1\d{10})$") || if($rU=~"^([2-9]\d{9})$") { xlog("L_INFO", " FROMASTERISK: This will become route(NORTHAMERICA); \n"); exit; ## to be removed } else { xlog("L_INFO", " FROMASTERISK: This will become route(INTERNATIONAL); \n"); exit; ## to be removed } # new call - send to Asterisk route(TOASTERISK); } Will this logic work? I haven't determined how to write route(NORTHAMERICA) or route(INTERNATIONAL) yet so I'm just logging to debug the logic and syntax. Thanks in advance.
