Hello, I am planing to release Kamailio v4.0.4 this week on Wednesday, Sep 2. If anyone has patching to push in branch 4.0, do it before noon GMT in that day. Also, if any developer is preferring another release day, just present the option on the mailing lists.

kamailio registering on back-end asterisk with username and password

by Paul Penev

I'm trying to implement a load balancer for asterisk servers using kamailio and the tutorial at http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb I must fit the balancer in an infrastructure without touching the other media servers (asterisk) which require a username/password authentication. The sample implementation constructs a register request from scratch, but does not handle authorization and thus fails. I cannot change the current sip servers and their configuration as these are a live system and I'm not allowed to touch it. I would really appreciate some hints on how to proceed. # Forward REGISTER to Asterisk route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport); $uac_req(furi)="sip:" + $au + "@" + $var(rip); $uac_req(turi)="sip:" + $au + "@" + $var(rip); $uac_req(hdrs)="Contact: <sip:" + $au + "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport) + ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send(); } Thank you, Paul.

Communicate with Kamailio through external application

by Grant Bagdasarian

Hello, When adding rows to the dispatcher table, the table in memory needs to be refreshed. Since we have multiple Kamailio instances running on different machines, I'd like to automate the process of reloading the table. Is there an easy way of doing this with an already existing module, which provides easy connectivity from the outside? Or do I need to write an application which basically sets up a SSH socket connection with the machine and sends the command "kamctl dispatcher reload" then exit? Not that hard either, but there might be a finer solution available. Regards, Grant

potential memory leak

by Dragos Oancea

Hello We've put Kamailio on a machine with a SIP-Proxy role, we replaced another SIP proxy implementation. We started with the default 4Mb of PKG Memory and 1024 Mb of Shared Memory but we had messages like these in the logs: 2013-09-26 13:48:26,939 ERROR: app_perl [kamailioxs.xs:371]: pv_sprintf(): pv_sprintf: Memory exhausted! 2013-09-26 13:48:50,267 ERROR: app_perl [kamailioxs.xs:371]: pv_sprintf(): pv_sprintf: Memory exhausted! 2013-09-26 13:48:51,822 ERROR: <core> [data_lump.c:197]: insert_subst_lump_after(): ERROR: insert_new_lump_after: out of memory 2013-09-26 13:48:51,823 ERROR: <core> [parser/contact/contact.c:194]: parse_contacts(): parse_contacts(): No memory left 2013-09-26 13:48:51,823 ERROR: memcached [../../parser/../ut.h:736]: pkg_str_dup(): could not allocate private memory from available pool 2013-09-26 13:48:51,823 ERROR: <core> [data_lump.c:373]: anchor_lump(): ERROR: anchor_lump: out of memory 2013-09-26 13:48:51,823 ERROR: <core> [dset.c:525]: rewrite_uri(): No memory left to rewrite r-uri 2013-09-26 13:48:51,823 ERROR: <core> [action.c:810]: do_action(): ERROR: do_action: memory allocation failure 2013-09-26 13:48:51,823 ERROR: <core> [msg_translator.c:2164]: build_res_buf_from_sip_req(): ERROR: build_res_buf_from_sip_req: out of memory ; needs 357 2013-09-26 13:48:51,823 ERROR: <core> [msg_translator.c:2164]: build_res_buf_from_sip_req(): ERROR: build_res_buf_from_sip_req: out of memory ; needs 376 Then we started kamailio like below, with 1024Mb of private memory (per process) : /opt/kamailio/sbin/kamailio -f /opt/kamailio/etc/kamailio//kamailio.cfg -w /opt/kamailio/core_dir/corefiles -P /opt/kamailio/var/run//kamailio.pid -m 1024 -M 1024 -u kamailio -g kamailio Then after about 4 days we realized that we have a steady increase of used memory ( in the output of free command the '-/+ buffers/cache:' row ), and we simply restarted the kamailio process. The machine has 12 Gb of RAM , we run with children=32 . 1gb of memory per process x 32 child processes means that we are over the physical capacity of the machine. The question is , are we in any danger of running out of memory on this box where we only run kamailio ? We don't want to reach the point where the kernel starts killing processes. Shall we suspect some memory leak in the app_perl module ? (we do some http queries over SSL from a perl script) Thank you. Regards, Dragos Oancea

next irc devel meeting - proposed for Sep 12, 2013

by Daniel-Constantin Mierla

Hello, I'm considering to have a new IRC devel meeting to plan a bit the development for the near future (among them, nail down goals and dates for next major release). The proposed date is next week on Thursday, at 14:00UTC, on #kamailio channel from irc.freenode.net. I create a wiki page for it at: - https://www.kamailio.org/wiki/devel/irc-meetings/2013b First thing to decide is the date and time, if it is something convenient for many people. If not, propose other dates and we will chose the one when most of the people are available. Also, feel free to add to agenda. For now I just created a basic list, I will add more myself as well.

DNS SRV when no NAPTR

Hi, I'm having problems connecting to a videoservice at seevia.no, because they have no NAPTR nor _sip._udp.seevia.no entry.

Websockets Keep-Alive

by Klaus Darilion

Hi! Question to the experts: Is keep-alive for the Websockets TCP connection automatically done by the Websockets Layer (client or server), or do I have to do it manually (nathelper pinging). Thanks Klaus
