Kamailio as pass through proxy?
by Rizwan Khan 01 Dec '14

01 Dec '14

Hi All, What we want to do is to by-pass the restrictions imposed by different ISPs etc. which normally block based on the port 5060 The SIP server(including SBC) is a commercial one running on port 5060, that we cannot change. It is already taking care of the NAT issues. We want to use Kamailio as the pass-thru proxy in front of the SBC just to receive the request on a random port, and then forward the request to the SBC internally being on the same private network. What would be the best way to do it? Any help will be highly appreciated. Rizwan Khan

Error when using function lookup_branches
by J Hazenberg 30 Nov '14

30 Nov '14

Hello, I'm runnig kamailio 4.2.0 and using the lookup_branches function from the register module to lookup all branches after a alias_db_lookup. The function seems to work fine but i see the following error in the log file just after the lookup: INFO: <core> [mem/f_malloc.c:599]: fm_free(): freeing a free fragment (0x7fad277fe110/0x7fad277fe148) - ignore INFO: <core> [mem/f_malloc.c:599]: fm_free(): freeing a free fragment (0x7fad277fcd38/0x7fad277fcd70) - ignore INFO: <core> [mem/f_malloc.c:599]: fm_free(): freeing a free fragment (0x7fad277fcd88/0x7fad277fcdc0) - ignore Code: alias_db_lookup("dbaliases"); if (!lookup_branches("location")) { This only happens when i have multiple branches, could this be a error in my script? Thanks, Jan

New Socket Per Call
by Andrew Mason 29 Nov '14

29 Nov '14

Hi All, I am looking to emulate a local proxy with Kamailio or OpenSips using a UAC and a UAS (each on separate machines ) but when initiate traffic from UAC to UAS using SIPp and defining a new socket for each call it does not force this between proxy and UAS but does between UAC and proxy - I think this may be a routing configuration? Thanks Andrew

[Kamailio 4.2.0] Carrieroute Routing Questions
by Massimo Varriale (IPZeta) 29 Nov '14

29 Nov '14

Hi Guys, I'm new on Kamailio and this list, so be patient with me :) I've built an almost "complete" working SIP server on Ubuntu 14.04 LTS. I told almost complete because my problem is with carrierroute module because I'm not understanding the routing file and where I should put the code to use function cr_route I would like to allow SIP calls/video between users for free and send calls to different external Gateways / Switches, etc based on the dialled destination. In particular, I can send outbound calls a prepaid platform that will allow to bill calls based on CLI validation, but in all my tests, it seems that calls are going out always to the IP address of the remote gateway found into the carrierroute table ignoring the SIP user I'm calling.....what is the correct routing? I'm finding some docs around there, but some refer to very old versions of Kamailio and some others are not clear to me. What's wrong with my routing logic? Thank you so much! Max route { # per request initial checks route(REQINIT); # NAT detection route(NAT); # handle requests within SIP dialogs route(WITHINDLG); ### only initial requests (no To tag) # CANCEL processing if (is_method("CANCEL")) { if (t_check_trans()) t_relay(); exit; } t_check_trans(); # authentication route(AUTH); # record routing for dialog forming requests (in case they are routed) # - remove preloaded route headers remove_hf("Route"); if (is_method("INVITE|SUBSCRIBE")) record_route(); # account only INVITEs if (is_method("INVITE")) { setflag(FLT_ACC); # do accounting } # dispatch requests to foreign domains route(SIPOUT); ### requests for my local domains # handle presence related requests route(PRESENCE); # handle registrations route(REGISTRAR); if ($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } # dispatch destinations to PSTN #route(PSTN); # CARRIERROUTE MODULE routing logic # check table for carrier default and domain default if(!cr_route("default", "default", "$rU", "$rU", "call_id")){ sl_send_reply("403", "Not allowed"); } else { # In case of failure, re-route the request t_on_failure("1"); # Relay the request to the gateway t_relay(); } # user location service route(LOCATION); route(RELAY); }

Shifting to github for git repository
by Daniel-Constantin Mierla 28 Nov '14

28 Nov '14

Hello, (cross posting, looking to get feedback for those with more experience on github options - playing the lazy guy, not searching much on the web so far). In order to move the main git repository to github (where the commits will be pushed by devs) and have a real-time mirror on our server (stored very likely on kamailio.org, but we will keep git.sip-router.org as domain for it), two things have to be sorted out: 1) real time propagation of commits from github to git.sip-router.org I discovered that github provides a web hook for this event - when a commit is pushed, then a http query is done to a given url. I thought of using it to trigger the mirroring from git.sip-router.org I couldn't find if we can use what Victor Seva configured on git.sip-router.org to push in real-time to github, which I guess is a script invoked on commit -- if we can turn that around, would be probably the easiest. 2) email notifications Anyone with extensive knowledge of how much the notification messages can be customized? Eventually trying to get the structure as much as possible to what we have now -- see an example: - http://lists.sip-router.org/pipermail/sr-dev/2014-November/026253.html I could notice that Jitsi (using github) commit notification has a format not far from ours: - http://lists.jitsi.org/pipermail/commits/2014-November/012937.html I can eventually talk with them if no one else here has related knowledge. Another option is to trigger the notifications from the mirror repository we will keep on git.sip-router.org Also, would be good to know if there are people with some spare time willing to help whenever needed with this migration. Reply here to have you in mind. Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda
