Re: [Kamailio-Users] How to know if a UAC is behind NAT after fix_nated_register() ?
by Pascal Maugeri 13 Jul '09

13 Jul '09

I answer to myself (it may help others) as I could test successfully the configuration below. Also there is a typo (isbflagset instead of isflagset): so when I detect a UA is behind NAT, I do: if (nat_uac_test("19")) { if (method=="REGISTER") { setbflag(7); fix_nated_register(); ... Then when my B2BUA sends invite to this UA I do (after lookup("location") ): lookup("location"); ... if (is_method("INVITE")) { if (isbflagset(7)) { setflag(5); Regards, Pascal On Mon, Jul 13, 2009 at 2:43 PM, Pascal Maugeri <pascal.maugeri(a)gmail.com>wrote: > I'm not that familiar with flag management. > > so when I detect a UA is behind NAT, I do: > > if (nat_uac_test("19")) { > if (method=="REGISTER") { > setbflag(7); > fix_nated_register(); > ... > > Then when my B2BUA sends invite to this UA I do (after lookup("location") > ): > > if (is_method("INVITE")) { > if (isflagset(7)) { > setflag(5); > > Is that correct ? > > BTW, regarding the flag number, is there a table of reserved numbers ?

Hello Marco, On 13.07.2009 14:28 Uhr, Marco Bungalski wrote: > Hello, Daniel, > > i know how to compile, but where to download the version with the bugfix > included? > if you fetch from svn the branch 1.5 then it has the fix. Here is a short description of how the versioning was done so far for kamilio (openser) from svn: - when a major version is released, a branch with the first two numbers in the version is created (e.g., 1.5) - for each minor version (including the .0 - corresponding to the major version) a tag is created with name of the three numbers in version - any fix for the major version is committed in the branch. Once a new minor release is out, a new tag is created. Therefore, the branch has all the time the most updated code for a specific major release. The tags are snapshots at the time of release. For the case of 1.5.x series: - there is one branch 1.5 - now there are two tags on svn: 1.5.0 and 1.5.1, soon there will be 1.5.2. - the tarballs are created from a svn checkout done as exampled in the wiki page I sent to you. probably reading a bit about svn (subversion) will help you. Anyhow, next major version will use GIT. Now, just to download the latest 1.5.x version, do: svn co http://openser.svn.sourceforge.net/svnroot/openser/branches/1.5 kamailio-1.5 You need subversion package installed. The continue installation as you do with the tarball.

[Kamailio-Users] How to know if a UAC is behind NAT after fix_nated_register() ?
by Pascal Maugeri 13 Jul '09

13 Jul '09

Hi A quick question, when I apply a fix_nated_register() to a remote user when he/she registers, how can I know later on if this user is behind NAT ? All my calls go through a B2BUA: Caller ------> kamailio/rtpproxy ------> B2BUA ------> kamailio/rtpproxy ------> Callee When my B2BUA calls a user, I want to know if this user is behind NAT or not. For now all the calls go through rtpproxy but I would like to apply this path only when user is behind NAT. Regards, Pascal

[Kamailio-Users] two more modules
by Daniel-Constantin Mierla 13 Jul '09

13 Jul '09

Hello, two of the last three modules that were not ported to use the new sip router core are ready now: nat_traversal and siptrace. Particularly, siptrace was refurbished, should catch now forwarded ACK. Before release, there are couple of new features that should get in trunk since sip route core offers support for such extensions: - ability to filter the ACK for negative replies issued by sl module in the script - ability to store stateless forwarded messages (now only stateful ones being stored) Testing is very much appreciated. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/

[Kamailio-Users] Kamailio 1.4.1 Configuration Issue
by dyerom AD 13 Jul '09

13 Jul '09

Good day everyone. As I am new to kamailio, I would like to ask help on the CFG file. I have successfully installed kamailio 1.4.1 but having problems to set it up on my desired functionality. Below is what i want to achieve. All sip clients (asterisk box, sip enabled box, pbx) should pass sip calls to my kamailio server. Clients connections to my Kamailio are via IP to IP. From my kamailio server i should be able to route them on my carrier, USA carrier and International Carrier. Connections to carrier is via IP to IP. I have set up Kamailio to support MYSQL authentication, its just that i have having problems to put my idea on the kamailio.cfg. Any sample working configurations similar to want I want to achieve is greatly appreciated. Thank you in advance for any support. Dennis Cristobal. jtom25(a)yahoo.com Feel safer online.

[Kamailio-Users] TCP supervisor process in Kamailio
by Pascal Maugeri 10 Jul '09

10 Jul '09

Hi I recently read the following in order to optimize OpenSER in handling TCP connections: "First, the TCP supervisor process must be given an elevated priority level in order to prevent anomalous behavior due to the Linux scheduler." First of all, as this is quite old paper (it refers to OpenSER 1.2), I'm wondering if such a tuning is still needed for Kamailio 1.5 branch ? If yes, how can I do this ? Regards, Pascal
