Hi, I would like ask you if there is a kamailio ims module documentation somewhere. I need some deeper information how some things are implemented, I have problem to setup NAT traversal with RTPproxy for our Kamailio IMS platform. There is no communication among the PCSCF and RTPproxy server over control udp sock. We tried unix socket also with the same results. Thanks palo73 http://nil.uniza.sk

Kamailio v3.1.3 Released

by Daniel-Constantin Mierla

Hello, Kamailio SIP Server v3.1.3 stable release is out. This is a maintenance release of latest stable branch, 3.1, that includes fixes since release of v3.1.2. There is no change to database schema or configuration language structure. Deployments running v3.1.0, v3.1.1 or 3.1.2 are strongly recommended to be upgraded to v3.1.3. For more details about version 3.1.3, visit: http://www.kamailio.org/w/2011/04/kamailio-v3-1-3-released/ Note: existing configuration files for installations on 64b operating systems may need to be updated to specify 'lib64' to the path where the modules are installed (to the value of parameter 'mpath'). See bottom note of the link provided above. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

tcp hangup

by Juha Heinanen

i have two sr proxies talking with each other over tcp. one is running 3.0 and the other 3.1. sometimes i notice that no sip requests or any other tcp packets get through from 3.0 sr host to 3.1 sr host. netstat on 3.0 sr host shows that tcp connection to 3.1 sr host is in ESTABLISHED state whereas netstat on 3.1 sr shows that the same tcp connection is in FIN_WAIT1 state. it takes several minutes before the hanging tcp connection is replaced by a new working one. there is no ip level connectivity problem between the two sr hosts. any suggestions on what might be going on? is there some known bug in 3.0 tcp implementation that could explain this? -- juha

SIP NOTIFY problem in "presence_dialoginfo" module?

by Klaus Feichtinger

Hello list, I have a special situation in which string characters of the "root-line" of the notify-body are overwritten by Kamailio. In detail: the root-line of the NOTIFY message sent to the subscriber looks like: <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" ll" entity="sip:117090@10.16.10.99"> instead of <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1" state="full" entity="sip:117090@10.16.10.99"> In other words: the string state="full" is overwritten by space characters. Therefore the message is no longer "valid" and the parser of the subscriber-user agent has problems.... The exact scenario in my use case is, that user agents can subscribe the events "presence" and "dialog" on Kamailio. The information about presence and dialog-states is published to Kamailio by PUBLISH messages from the user agents themselves. Kamailio does not have to generate this information itself. In the following lines I have an excerpt of the signalisation: 1) initial subscription of party A, 2) the responded notification (without body) 3) subscription of party B 4) the responded notification (with body) 5) a publish message of the subscribed party B with actual dialog information and 6) the notification with body to the subscriber A. 1) Initial SUBSCRIBE message of party A: ======================================SUBSCRIBE sip:117090@10.16.10.99 SIP/2.0 Via: SIP/2.0/UDP 10.16.10.93:5060;rport;branch=z9hG4bK1411449981 From: <sip:117093@10.16.10.99>;tag=2453899634-24035392-1301468026894 To: <sip:117090@10.16.10.99> Call-ID: 2442490492-24035392-1301468026894(a)10.16.10.93 CSeq: 20 SUBSCRIBE Contact: <sip:117093@10.16.10.93:5060> Max-Forwards: 70 User-Agent: SipTapi Expires: 3600 Event: dialog Content-Length: 0 2) Responded NOTIFY message from Kamailio: ========================================NOTIFY sip:117093@10.16.10.93:5060 SIP/2.0 Via: SIP/2.0/UDP 10.16.10.99;branch=z9hG4bK7cc7.08e060b6000000000000000000000000.0 To: sip:117093@10.16.10.99;tag=2453899634-24035392-1301468026894 From: sip:117090@10.16.10.99;tag=a23c71953194c2c72e41c4d20e4f7127-86e1 CSeq: 1 NOTIFY Call-ID: 2442490492-24035392-1301468026894(a)10.16.10.93 Content-Length: 0 User-Agent: kamailio (3.1.2 (i386/linux)) Max-Forwards: 70 Event: dialog Contact: <sip:10.16.10.99:5060> Subscription-State: active;expires=3670 3) Initial SUBSCRIBE message of party B: ======================================SUBSCRIBE sip:117093@10.16.10.99 SIP/2.0 Via: SIP/2.0/UDP 10.16.10.90:5060;rport;branch=z9hG4bK4016956575 From: <sip:117090@10.16.10.99>;tag=2605346227-26329880-1301468174702 To: <sip:117093@10.16.10.99> Call-ID: 2982039389-26329880-1301468174702(a)10.16.10.90 CSeq: 20 SUBSCRIBE Contact: <sip:117090@10.16.10.90:5060> Max-Forwards: 70 User-Agent: SipTapi Expires: 3600 Event: dialog Content-Length: 0 4) Responded NOTIFY message from Kamailio (with version number "00000000000"!!!!): ==============================================================================NOTIFY sip:117090@10.16.10.90:5060 SIP/2.0 Via: SIP/2.0/UDP 10.16.10.99;branch=z9hG4bK10e8.31cb2284000000000000000000000000.0 To: sip:117090@10.16.10.99;tag=2605346227-26329880-1301468174702 From: sip:117093@10.16.10.99;tag=a23c71953194c2c72e41c4d20e4f7127-5f56 CSeq: 1 NOTIFY Call-ID: 2982039389-26329880-1301468174702(a)10.16.10.90 Content-Length: 593 User-Agent: kamailio (3.1.2 (i386/linux)) Max-Forwards: 70 Event: dialog Contact: <sip:10.16.10.99:5060> Subscription-State: active;expires=3670 Content-Type: application/dialog-info+xml <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="00000000000" state="full" entity="117093(a)10.16.10.99"> <dialog id="3375446242-26591296-1301467877329(a)10.16.10.93" call-id="3375446242-26591296-1301467877329(a)10.16.10.93" direction="initiator"> <state>terminated</state> <remote> <identity>sip:019992116002@10.16.10.99</identity> <target uri="sip:019992116002@10.16.10.99"/> </remote> <local> <identity>sip:117093@10.16.10.99</identity> <target uri="sip:117093@10.16.10.99"/> </local> </dialog> </dialog-info> 5) The subscribed party is sending a PUBLISH message with following information: ============================================================================PUBLISH sip:117090@10.16.10.99 SIP/2.0 Via: SIP/2.0/UDP 10.16.10.90:5060;rport;branch=z9hG4bK348084694 From: <sip:117090@10.16.10.99>;tag=3644648667-26329880-1301468223499 To: <sip:117090@10.16.10.99> Call-ID: 332031778-26329880-1301468223499(a)10.16.10.90 CSeq: 20 PUBLISH Max-Forwards: 70 User-Agent: SipTapi Content-Disposition: render;handling=required Expires: 3600 Event: dialog Content-Type: application/dialog-info+xml Content-Length: 592 <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="4" state="full" entity="sip:117090@10.16.10.99"> <dialog id="2769397361-26329880-1301468223108(a)10.16.10.90" call-id="2769397361-26329880-1301468223108(a)10.16.10.90" direction="initiator"> <state>confirmed</state> <remote> <identity><sip:116001@10.16.10.99></identity> <target uri="<sip:116001@10.16.10.99>"/> </remote> <local> <identity>sip:117090@10.16.10.99</identity> <target uri="sip:117090@10.16.10.99"/> </local> </dialog> </dialog-info> 6) Status informative NOTIFY message from Kamailio (built from the PUBLISH message above -

Suggestion dialog module / $dlg_ctx() problem.

by Alexandre Abreu

Hello. Using K 3.1.2. Before the setflag() that creates the dialog, I tried to use: $dlg_ctx(flags) = 1; Mar 30 12:29:03 devel kamailio: ERROR: dialog [dlg_var.c:165]: unknown PV name flags Mar 30 12:29:03 devel kamailio: ERROR: <core> [pvapi.c:565]: pvar "dlg_ctx" has an invalid name param [flags] Mar 30 12:29:03 devel kamailio: ERROR: <core> [pvapi.c:720]: wrong char [)/41] in [$dlg_ctx(flags)] at [14 (5)] Mar 30 12:29:03 devel kamailio: : <core> [cfg.y:3409]: parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 308, column 9-23: unknown script pseudo variable $dlg_ctx(flags) Right now, my goal is to add the user-agent content header ($ua) from caller/callee and list them through 'dlg_list_ctx'. I would suggest something like that: Request route: $dlg_ctx(set->ua_src) = $ua; On reply route: $dlg_ctx(set->ua_dst) = $ua; dlg_list_ctx: . ua_src:: X-Lite 3.0 build 666 ua_dst:: Linksys PAP2 . Does this suggestion make sense? Using another approach is it possible to execute this today? Thanks, Alexandre

library dir for x86_64 - lib or lib64

by Daniel-Constantin Mierla

Hello, iirc this was at some point discussed, however, I want to go through it again. Many x86_64 distros expect libraries to be placed under a lib64 directory. For example the RPM spec file language returns /usr/lib64 for %{_libdir} variable. In the master branch I committed a patch that does this detection. As I saw some people saying that 'lib' should be the default also for x86_64, my question is then what do you think we should use? Using 'lib' will definitely make building rpms fail unless we do a patch specific for these distros. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com
