>You mean you've added the users to the subscriber table? Yes i added User1 and User2 in the subscriber's mysql table. Xlite conf : usr : User1 psw : xxxx Domain : 10.10.10.2 usr: User2 psw : xxxx Domain : 192.168.0.2 In mysql table i added : User2 with xxx psw and 192.168.0.2 domain. (don't really know if it is the righ way...!?) It seems the registering request are fine, below are the wireshark captures for user1 and user2 : http://www.nabble.com/file/p23555745/User1_Register.jpg http://www.nabble.com/file/p23555745/User2_Register.jpg Etheir i try to call from User2 to User1 or User1 to User2 i got nothing. On XliteUser2 i tried for the call : User1(a)10.10.10.2 >You've enabled auth in the cfg given below, so this is the expected behaviour. >Your UA should reply with the proper credentials, then the call should be >established. Take a look to the log file of the kamailio, and do a sip trace >(e.g. with ngrep -W byline port 5060) to get more information about the >eventual problem.

Hi, I am getting the following error when kamailio wants to connect to mysql within a simple perl program. "mysql" module is already loaded in the config file. Is there any modparam for mysql that has to be set? ERROR:core:XS_OpenSER__Message_log: perl error: Can't locate object method "connect" via package "DBI" at /etc/openser/test.pl line 17. simple perl program: #!/usr/bin/perl use OpenSER; use OpenSER::Constants; sub run { ??? } 1 Thanks, A.

[Kamailio-Users] kamailio multi-domain
by karhu 14 May '09

14 May '09

Hello, First of all i would like to say i am a newbee in Kamailio :). Here is my network configuration : User 1 User2 10.10.10.3 10.10.10.2 192.168.0.2 192.168.0.10 -----------------*KAMAILIO*----------------- User1 and User2 are registered in mysql. When i installed Kamailio, i edited kmctlrc to have SIP_DOMAIN = 10.10.10.2. I am using XLite Siphone for both users. When User 1 is registering to Kamailio there is no problem, but when User2 try to do the same i get 407 Proxy Authentication Required.. What i would like to do is User1 call User2 trough kamailio. Obviously i activated nathelper module and started rtpproxy. Do i need to configure multi-domain module ?

[Kamailio-Users] x-lite 3.0 on linux
by Daniel-Constantin Mierla 14 May '09

14 May '09

Hello, during last weeks while testing the kamailio (openser) modules with sip-router core I got x-lite 3.0 working on linux (ubuntu) with wine 1.1.20. I posted guidelines at: http://appdb.winehq.org/objectManager.php?sClass=version&iId=16413 Voice, IM&Presence seem to work just fine. Video was not tested as I couldn't make any wine application see the video cam, although it is working fine on linux with skype or ekiga. For me it is a great tool to test the presence, hope it will be useful for some of you as well. Apart of x-lite, I got other sip softphone working with wine: - pangolin - works fine, but the presence status changes are not sent to server (no PUBLISH) -- might be a bug in the software, maybe someone running it on windows can confirm it or not - zoiper communicator rc1 free edition for windows - linux version seems to be available now, but requires to register with their site Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/

[Kamailio-Users] kamailio and/or ser 3.0 with sip router core
by Daniel-Constantin Mierla 14 May '09

14 May '09

Hello, long awaited period of SIP Router integration phase is more and more approaching the end. Apart of 4 modules that are not integrated yet from Kamailio - seas, siptrace, uac_redirect and nat_traversal (work being undertaken) -- the rest of 88 modules are ready for http://sip-router.org core. I have created a page to collect guidelines for the default Kamailio configuration file used with sip-router. I invite all of you to test it, not only this one, but your private configs as well. http://sip-router.org/wiki/migration/kamailio-3.0-config Feel free to add to the wiki page or post questions about it to sr-users(a)lists.sip-router.org. This is a new list created for users of sip-router project, you can subscribe to it at: http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users At this stage, sip router can be used with modules from both Kamailio (OpenSER) and SER projects, mixed in same instance at the same time. Therefore you can choose the best ones that fit your needs. For Kamailio (OpenSER) users there is a page that tries to collect new features they got from SER side (still a lot to add there, hope ser developers will contribute what they find missing). Another page collects links for ser and kamailio users to find what the other project brings: http://sip-router.org/wiki/migration/new-features-for-k-users http://sip-router.org/wiki/features/inherited-features It was not only integration work in the past months, sip router has quite a bunch of brand new feature. The wiki page to collect the summary is available at: http://sip-router.org/wiki/features/new-in-devel Jan just set online documentation portal, available for web browsing: http://sip-router.org/docbook/sip-router/branch/master/ Common modules are located in directory 'modules' while kamailio and ser specific modules can be found under module_k and modules_s. Project's wiki portal got also good content and it is under heavy work -- note that everyone can contribute to wiki: http://sip-router.org/wiki Couple of core and tm features are not yet integrated or not exactly as they were in Kamailio. Please report the ones you are missing in your config at: http://sip-router.org/wiki/devel/kamailio-integration#tm_and_core_extensions It is the place that should set the priority rank for integration. I hope that in 1-2 months time frame to get into beta stage and prepare a stable release. Many thanks for those that allocated resources to make things evolve to this stage and many thanks in advance for those that will start testing and help improving the sip router project. Beware that is still very early stage and not recommended for production. Cheers, Daniel PS. Codename 3.0 refers to Kamailio (OpenSER) or SER using sip router core, there is not a stable release yet. -- Daniel-Constantin Mierla http://www.asipto.com/

[Kamailio-Users] dialplan subst issue
by Andreas Granig 14 May '09

14 May '09

Hi all, I was playing around with dialplan module (kam 1.4) for the first time and it seems that the repl_exp doesn't handle back references correctly: mysql root@kamailio> select * from dialplan\G *************************** 1. row *************************** id: 1 dpid: 1 pr: 1 match_op: 1 match_exp: @voicebox\.local$ match_len: 0 subst_exp: ^sip:(.*)$ repl_exp: sip:xx_\1_yy attrs: voicebox 1 row in set (0.00 sec) In my config, I do: dp_translate("1", "$ru/$var(dptest)"); xlog("L_INFO", "DP result='$var(dptest)', attr='$avp(s:dialplan_attr)\n"); and the result is: DP result='sip:xx_user@voicebox.local', attr='voicebox' So the string after the back reference ("_yy" in this case) is not inserted. Any ideas? Andreas
