[Kamailio-Users] Mediaproxy and SDP-mangle

by Cosimo Fadda

Hi everybody, I have a sever inside a DMZ with a private IP address (10.20.30.40) reachable from the outside with a Public IP (90.80.70.60) Natted 1:1 to the private IP. I want to setup mediaproxy on this server, but since I cannot configure it with the public IP, in the resulting SDP messages the Private IP will appear . Can I use the function: sdp_mangle_ip("10.20.30.40","90.80.70.60"); to correct this behaviour? Or there is another way to run mediaproxy in this scenario? Thanks in advance, Cosimo

[Kamailio-Users] [Fwd: [SR-Dev] git repository online]

by Daniel-Constantin Mierla

FYI -------- Original Message -------- Subject: [SR-Dev] git repository online Date: Tue, 18 Nov 2008 02:18:34 +0100 From: Andrei Pelinescu-Onciul <andrei(a)iptel.org> To: sr-dev(a)lists.sip-router.org As you probably have noticed the git repository for sip-router is now online. It was started from ser core and tm. git urls: git://git.sip-router.org/sip-router (read only) http://git.sip-router.org/sip-router (read only, slower, git://... recomended) ssh://git.sip-router.org/sip-router (read write but account on git.sip-router.org needed) Web interface: http://git.sip-router.org/cgi-bin/gitweb.cgi Branches acl: the repository is setup so that you can write/commit only to the following branches: <your_username>/.* tmp/.* master We'll add access to more branches as needed (I've added this rules to avoid creating lots of "root" branches by mistake, e.g. git pull from a local branch without a refspec). Please create the commit messages following the git convention (start with one short line, preferably less then 50 chars summarizing the changes, then one empty line and then a more detailed description). See: http://www.kernel.org/pub/software/scm/git/docs/user-manual.html#creating-g… http://www.tpope.net/node/106 Quick git introduction: # clone the repo into the sip-router directory git clone git://git.sip-router.org/sip-router cd sip-router git branch -a # show all branches # create a local branch based on origin/andrei/mod_f_params git checkout --track -b my_branch origin/andrei/mod_f_params git log # see commit log git log --pretty=oneline # only the first line from each commit vim Makefile.defs git add Makefile.defs git commit # or git commmit -a to skip the add step and commit all # changed files # push changes back (note you need ssh access for this) # note: the next command will fail, unless your username is andrei :-) # publish changes on the local "my_branc" to the remote # andrei/mod_f_params git push origin my_branch:andrei/mod_f_params # or push them into the master branch if you are sure about them git push origin my_branch:master For more info about git try: http://git.or.cz/gitwiki/GitDocumentation and if you want to know how it works: http://eagain.net/articles/git-for-computer-scientists/ (highly recommended) CVS access: CVS_SERVER="git cvsserver" cvs \ -d :ext:andrei@git.sip-router.org/sip-router co master (instead of master you can use any other branch name that doesn't include a '/') The initial checkout takes a while, but after that cvs update seems fast enough. SVN access: unfortunately we do not have it. It looks like the git svnserver is in the project stage (there is some python code but not runnable yet). There is a way around it, but it would be quite complex to setup: a git to svn gateway and then svn to git imports. Other repositories on git.sip-router.org: ser - entire ser updated from cvs ser_core - only ser_core, automatically updated from cvs, read-only test - test repository, contains an early sip-router version, it has the same access rules as sip-router (if you have something you want to test, please use it rather then trying directly on sip-router). Special thanks go to Jan, who not only did setup git.sip-router.org (including automatic cvs sync for some of the repos), but he's also hosting it on one of his private machines.

[Kamailio-Users] Issues with OpenSER 1.3.2

by Chris Tooley

I'm having an issue with 1.3.2 where it's adding "100rel" to the Supported header when it wasn't previously there. I'm sure this is something I'm doing wrong, but I can't tell what it would be.

[Kamailio-Users] Problems with counter $var(i)

by Ricardo Martinez

Sorry ¡ i forgot to put the subject. Hello list. I'm having some problems trying to build a counter for my kamailio.cfg file. This is what I have.. main() ... load avp from radius} var(i)=0; route(3); ... route[1] { t_on_failure("1"); if (!t_relay()) { sl_reply_error(); }; xlog("L_INFO","[$ci] $rm t_relay a $ru"); exit; } route(3) ... $var(nr)=$avp(s:caller_nr); If ( var(i) < $var(nr) ); $var(i) = $var(i) + 1; route(1); else exit; failure_route[1] { xlog("L_INFO", "[$ci] $rm:$ru failure_route\n"); if (t_was_cancelled()) { xlog("L_INFO", "[$ci] $rm:$ru t_was_cancelled en failure_route\n"); exit; } if (!next_gw()) { xlog("L_INFO", "[$ci] No hay mas gateways para $rm:$ou\n"); route(3); } else { xlog("L_INFO", "XXXXX"); } t_on_failure("1"); t_relay(); } After I restart the service the first time a call arrives the counter seems to go OK, the counter goes from 0 to 2 (if the caller_nr=3). But the second time the $var(i) at the main and route(3) it's = 0, but in the failure_route it keeps the value = 3. What I'm doing wrong? Can someone help me here? Thanks Ricardo Martinez.-

[Kamailio-Users] Problems with USRLOC not being 0, can not make p2p calls

by Ali Jawad

Hi All If I have modparam("usrloc", "db_mode", 0) I can make calls between two users that are currently using my openser installation. If I set modparam("usrloc", "db_mode", 1) or modparam("usrloc", "db_mode", 2) It does not work any more and I get 408 errors, although the entries are written to the location table in the database and openserctl ul show -brief does show the users. Any ideas ? Thanks

[Kamailio-Users] Engaging rtpproxy

by Graham Wooden

Hi list, I currently don¹t proxy audio nor have any plans to for all calls, except for the "302 Redirect", where I need kamailio to become a b2bua with RTPproxy (or for the record CALEA). However, I can¹t seem to get the ³if² statement down on where ³engage_media_proxy² gets called without doing it for all outbound calls. What is the best way to identify a call that was from a SIP client that issued a 302? My last effort was: if ( uri == mysqlf && is_method("INVITE") ){ But that seemed to get every call. Any guidance would be appreciated, thanks. -graham

well put dan! I really don't understand why you would bother bringing this to our attention at all Henning.
