auth users using inmemory lookups

by Grant Bagdasarian

Hello, We're currently using the auth_db module and calling the function auth_check to check the Authorization header and authenticate the request. We moved most of our code to in-memory lookups (using htable), since we do not want our Kamailio servers to be DB dependent. Just to be sure, if we move the authentication to in-memory lookups we should use the auth module and call the pv_auth_check function instead right? The passwords in our users table are all stored in MD5, so we basically just have to put this table in a htable, and call the pv_auth_check and pass it the hashed password and the flag 1? Regards, Grant

Problem with t_relay() and VPN tunnel

by Carlos Ruiz Diaz

Hi, I have two SIP servers, *A* and *B*, connected each other though a OPENVPN tunnel. The server *B* needs to t_relay() every SIP message containing the method MESSAGE to the server *A* but these messages never reach destination. I have tested the tunnel connectivity and works fine. I wrote a Perl script (located in *B*) that sends SIP MESSAGES to Kamailio (located in *A*) trying to figure out what is happening but these messages are received by *A* and processed correctly but when *B* does the same from Kamailio, it is never received. Here is the route part of kamailio.cfg in *B*: Observation: ($rU == "1004") result is *true* * if(is_method("MESSAGE")) { if($rU == "1004") { xlog("L_INFO","En 1004"); rewritehost("10.8.0.1"); if (!t_relay()) xlog("L_INFO","MIO Error en t_relay"); t_reply("200", "Ok"); xlog("L_INFO","MIO despues rewrite"); exit; } .....* The perl script that WORKS: *$msg = 'MESSAGE sip:1004@192.168.1.2:5060 SIP/2.0 Via: SIP/2.0/UDP 192.168.1.2 From: "2002" <sip:2002@192.168.1.2 <sip%3A2002(a)192.168.1.2>>;tag=1837944796 To: <sip:1004@192.168.1.2 <sip%3A1004(a)192.168.1.2>> Call-ID: 19722852989(a)192.168.1.2 CSeq: 15773 MESSAGE Contact: <sip:2002@**PublicIP-protected**:5060> Max-Forwards: 29 User-Agent: DBL Content-Type: text/plain Content-Length: 34 +595981[protected] hello from kamailio '; use IO::Socket; my $sock = IO::Socket::INET->new( Proto=>'udp', PeerHost=>'192.168.2.102', PeerPort=>'5060'); print "Sending msg $msg\n"; $sock->send($msg) or die "error sending $!\n"; *Please help! Thanks in advance. Carlos.

How to get the count of active calls handled in kamailio.

by vivek＠advaitamtech.com

Hi, I would like to know how many active calls are handled in kamailio server at a given point of time(concurrent calls). In the few older post it was mentioned to use "dialog" module for these statistics. In dialog module , there is a function called "active_dialogs" , which solves my requirement. But it is not clear how to use it. Can anybody help me out in this? Thanks, Vivek.

Kamailio v4.3.7 Released

by Daniel-Constantin Mierla

Hello, Kamailio SIP Server v4.3.7 stable release is out. This is a maintenance release of an old stable branch, 4.3, that includes fixes since release of v4.3.6. There is no change to database schema or configuration language structure that you have to do on installations of v4.3.x. Important note: unless some major regression is discovered in the near future, this is the latest release to be done from branch 4.3, which is no longer to be officially maintained. Therefore it is strongly advised to consider upgrading to 4.4.x or 5.0.x series. For more details about version 4.3.7 (including links and guidelines to download the tarball or from GIT repository), visit: * https://www.kamailio.org/w/2017/06/kamailio-v4-3-7-released/ RPM, Debian/Ubuntu packages will be available soon as well. Note: the latest stable branch is 5.0, at this moment with its latest release v5.0.2. See more details about it at: * https://www.kamailio.org/w/kamailio-v5-0-0-release-notes/ Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/miconda - http://www.linkedin.com/in/miconda

Releasing Kamailio v4.3.7

by Daniel-Constantin Mierla

Hello, I am planning to release Kamailio v4.3.7 very soon, likely tomorrow, based on the last version of branch 4.3. This should mark the end of official maintenance for branch 4.3, so if no major regression discovered in following few weeks, it will be the last release in 4.3 series. If there is something you know it needs to be pushed in branch 4.3, write back to mailing list.

Better place to change the FROM header for every INVITE

by Emanuele Gambaro

Hi I need to change the FROM header for every invite and replace the caller username with another data taken from mysql database. Which is the best place in kamailio routes to do a uac_replace_from ? It is correct to change the FROM header before the dialog creation, in “RELAY” route, just before the t_relay()? Thank you -- Emanuele Gambaro --- email: emanuele.gambaro(a)pynlab.com skype: sarbyn_work OpenPGP Key: https://goo.gl/fdeVnI

Help detecting t.38 and routing accordingly

by Tim Bowyer

Hi All, Trying to work out a way to detect and re-route inbound calls which negotiate or contain t.38 SDP to answer/process faxes efficiently. Plan is to put Kamailio in front of a quantity of FreeSwitch servers - most virtual, others physical. Virtual servers will handle inbound faxes which negotiate t.38, and physical servers will answer ulaw/alaw faxes with mod_spandsp. The bulk of inbound faxes negotiate t.38, but in order to scale our inbound system we need some way to work out which way to send the calls prior to the dispatcher. Many thanks for your help in advance, Tim

by Mojtaba

Is it not better to use SEMS as SBC in the front of your network? And all P/S/I/CSCF have the private IP address. Thanks --Mojtaba Esfandiari.S
