Vicente. Thanks for solving my problem. :-) You pointed me in the right direction. The mistake I made was this: ================== When reading the website Create user access table: * create a new table in Kamailio (OpenSER) database name ob_users: CREATE TABLE `ob_users` ( `SYSID` int(11) NOT NULL auto_increment, `USERID` varchar(15) NOT NULL, `PASSWORD` varchar(15) default NULL, PRIMARY KEY (`SYSID`) ); I created a new database ob_users with a table ob_users, in stead of inserting the table into the database openser.

I'm trying to install Siremis 1.0.0 to work with Kamailio 3.0 and I'm having some problems which hopefully somebody can help with.

How do deal with a lost ACK and TM
by Geoffrey Mina 21 Jun '10

21 Jun '10

I am not 100% sure I fully understand my issue, but I think I'm on the right track. I have a situation where Asterisk will drop calls a few seconds after they are set up. What I believe is happening: a=asterisk k=kamailio k --> INVITE --> a a --> 100 TRYING --> k a --> 183 RINGING --> k a --> 200 OK --> k k --> ACK -->a (this packet is never received by asterisk) a --> 200 OK (retransmit) -->k a --> 200 OK (retransmit) -->k a --> 200 OK (retransmit) -->k a --> no response to critical packet - terminating call It doesn't appear that Kamailio is retransmitting the ACK. I would think that would be part of the TM module, but perhaps I am not using it properly. Is this possible or is there something else going on? Thanks.

Kamailio on Solaris(OpenSolaris)
by Daniel Cardoso Alves 21 Jun '10

21 Jun '10

Hi people, I am trying to install kamailio in a server with OpenSolaris (SunOS sun-test 5.11 snv_83 i86pc i386 i86pc), to make some tests, performance, capacity, etc. I tried to compile on Solaris but, it dont works perfectly. :) On the Internet and in the Manuals, I saw that there is a port from kamailio to solaris, but I dont find where to get this. Docs: INSTALL Supported architectures: - Linux/i386, Linux/amd64, Linux/armv4l, - FreeBSD/i386, OpenBSD/i386, NetBSD/sparc64 - Solaris/sparc64, Solaris/i386 So I have some questions: Is there a port to Solaris? Can I to compile Kamailio on Solaris (OpenSolaris)? Are there any manuals to install kamailio on Sun Machines? By the way, Can anybody tell me if the performance and capacity of kamailio on the solaris is better than linux? Thanks...

TM clarifications
by David 21 Jun '10

21 Jun '10

Hello, I am using Kamailio 1.5.4. I read RFC3261 section 17 and the TM doc, I had a few questions : Does t_relay() manage both the client and server transactions for the packet being forwarded ? Meaning it would absorb retransmissions it receives and would retransmit the relayed message when needed ? Do I need to call t_release() when I call t_relay () ? Where would I use t_checktrans(), t_release() and t_newtran() ? My understanding is that if I want to receive a packet and process it locally without forwarding it, I should use t_newtran(). This would be good for things such as PUBLISH, PRESENCE and REGISTER ( even though it's not a good idea ). So when do I release the transaction ? In the reply route ? In the same run as I call t_newtran() ? Does t_checktrans() absorb retransmissions that were started with t_relay and t_newtran? If you have any material that I could read that would help me better understand the TM module, please say so. Thanks, David

No voice issue with NAT
by JinKevin 20 Jun '10

20 Jun '10

Hi, My kamailio and application server are with Public IPs so the system uses nathelper without RTPProxy. It works with the eyebeam behind the ADSL router, but I cannot hear any voice ( ethereal capture on the PC shows no RTP from the application server) when try it in a Hotel or with a 3G data card.
