sip_trace vs uac_reg
by James Cloos 22 Feb '16

22 Feb '16

I've started adding sip_trace to my kamailios, and mostly have it working, but cannot figure out how to capture the outgoing calls from uac_reg. I had to add: reply_route { sip_trace(); } onsend_route { sip_trace(); } to capture those packets. What *_route {} does uac_reg target for its outgoing packets? I read uac_reg.[ch], and see that it uses the t_request method from tm's struct tm_binds. And that the methods are defined via a call to load_tm_api(), and that t_request defaults to the request() function in tm/uac.c. But I don't see from that which route chunk it uses. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

Upgrade 4.0 to 4.3
by Daniel W. Graham 22 Feb '16

I'm looking to upgrade a system from 4.0 to 4.3 I see the various upgrade docs https://www.kamailio.org/wiki/install/upgrade/4.0.x-to-4.1.0 https://www.kamailio.org/wiki/install/upgrade/4.1.x-to-4.2.0 https://www.kamailio.org/wiki/install/upgrade/4.2.x-to-4.3.0 If the updates are completed as shown in the docs, can I jump directly to 4.3? Anything to look out for? Thanks! -dan

db_cluster.so module and kamctlrc DBHOST= field
by Derek Bolichowski 22 Feb '16

22 Feb '16

Hi there, New user to Kamailio here. We currently have it up and running in a virtualized environment with 1 Kamailio sever, 1 Asterisk server and 1 MySQL server. I'm currently writing install scripts to make deploying new nodes/servers easy and to keep settings the same across the board. I've chosed to load the db_cluster.so module in kamailio.cfg, as we will have 2x MySQL servers in master-master replication which will contain the 'kamailio' and 'asterisk' tables. I've just hit a stumbling block - in `kamctlrc`, there is a field called `DBHOST=`. How can I reference my cluster here? In kamailio.cfg, I simply define DBURL as "cluster//<clustername>". What is the syntax for 'DBHOST=' in 'kamctlrc'? Can I reference the cluster? Can I have 2 separate DBHOST= lines? Looking for some guidance on this one. Thanks, Derek B.

I have now spent some time to reproduce the issue. First of all: I had to adapt module reg_mod.c in ims_registrar_pcscf, because it containes a hardcoded P-CSCF address: str pcscf_uri = str_init("sip:pcscf.ims.smilecoms.com:4060"); which is only valid for smilecoms. Did you also change that? Then I got exactly the same problem. I found that the P-CSCF config causes in the part "# Check for Subsequent requests:" a reject " sl_send_reply("404","Not here");" I have doubts that this is correctly designed and have to dig deeper into the logic of the config-file. Fact is: the NOTIFY request does not contain a Route header and as it not an ACK it goes straight to the reject. Maybe any IMS expert can shed some light on this code as shown below: # Check for Subsequent requests: if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if ($route_uri =~ "sip:mo@.*") { setflag(FLT_MO); } if(!isdsturiset()) { handle_ruri_alias(); } # RTP-Relay, if necessary route(RTPPROXY); t_relay(); } else { if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); } exit; BR Franz

Make SIP session between two kamailio servers
by Cockhootec Yahrabee 21 Feb '16

21 Feb '16

Hi everyone, I am curious if there is a way to make SIP session between two kamailio server instances eg. if there is way to use kamailio as an SIP client and SIP server at the same time. I am thinking about the following configuration: kamailio main server ----- kamailio server B ----- SIP client B1 | | | kamailio server A ----- SIP client A2 | | | SIP client A1 I want to be able to make SIP session between: SIP client A1 : SIP client A2 kamailio server A : kamailio server B SIP client A1 : SIP client B1 (this would be great) If there is currently no way to do this do you think that it would be possible to create the module which will support this kind of functionality? Thanks in advance for the replies

Hello Cristina, > In the attach you can find the trace of the registration. I have checked your tracefile and confirm: that is a problem which needs further debugging. Up to now I did not activate "WITH_REGINFO" in my installation, therefore I cannot compare. If I find time (this weekend) I will do that and come back with the findings. BR Franz

rfc: kamailio.cfg polishing for v4.4
by Daniel-Constantin Mierla 20 Feb '16

20 Feb '16

Hello, wondering if people feel it is need to polish the current default kamailio.cfg, to prepare the version for next major release. It can be browsed online at: - https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg It is mainly about very common scenarios that are encountered out there and we should deal with by default. Have in mind that there are the basic and advanced versions of kamailio.cfg in the etc folder. Also, I am looking for tunings for core parameters and module parameters that make the config more suitable for common use case. Speaking of those extra config files, I think the kamailio-advanced.cfg and kamailio-basic.cfg should be deployed in shared doc folder, not being active configs upon default installation.
