[Serusers] Use of @IP source in ser.cfg
by inge 08 Apr '09

08 Apr '09

Hi all, I know that it's possible to use a variable in XLOG for print out the IP Source. But is it possible to work on @IP_SRC (use if, avp, etc.) in ser.cfg ? I can work with search() but it's not very flexible to have dynamic test with database for example. My SER version is 0.9.6. Regards, Adrien

[Kamailio-Users] Path and received parameter
by Klaus Darilion 07 Apr '09

07 Apr '09

Hi! During REGISTER processing I call add_path_received() in the outbound proxy. Now if the INVITE is routed from main proxy to the client (via the OBP), the OBP as to read the received parameter from the Ruote header and use this value as destination URI. Is there a function available to perfomr this action or do I have to do it manually (parsing Route header to the get parameter)? thanks klaus

hi all please, can you tell me is this scenario correct i want to use ser as a load balancer for two asterisk servers. i have two users which are registred in both astersik servers with the same extensions (sip.conf and extensions.conf are the same for the asterisk servers) i have a user registred in the ser server. i imagine load balancer like: when the ser user calls an asterisk extension .the ser redirect this call to one of the asterisk.when the ser user recall the extension the ser will redirect the call to the other asterisk please tell me if i am wrong and if possible give me the correct scenario. thank you

[Kamailio-Users] Nethelper Causes Kamailio to Crash
by Carlos A. Alvarez 06 Apr '09

06 Apr '09

I am running into a situation where the nathelper module is causing openser/kamailio to crash. The crash occurs when opensbc sends and invite to openser with an extra CR in the message body. I already contacted the opensbc folks about this. I just wanted you all to be aware that this could cause serious service interruptions. Error log: kernel: [599650.771067] kamailio[25461]: segfault at 18 ip b7a0a6c7 sp bfbaaa70 error 4 in nathelper.so[b79f7000+18000] Sample invite sent to kamailio..

[Kamailio-Users] LCR Configuration Confirmation
by geoffreymina＠gmail.com 06 Apr '09

06 Apr '09

Hello, I am modifying my LCR setup and just wanted to get some confirmation that I am following best practices. I am a I am loading up 18,500 routes into the table which all belong to a single group. There will be a single route in a second group which all non-matches will fail over to. That being said, this is what my configuration looks like: modparam("lcr","lcr_hash_size", 20000) modparam("lcr","fetch_rows", 5000) This server has 8G of RAM and I am currently using 4M of private memory (#define PKG_MEM_POOL_SIZE 4*1024*1024 ). Thanks, Geoff

Re: [Kamailio-Users] another instance of kamailio on the same machine

thank you ovidiu I do not have an init scrip, I start and stop using the "kamctl stop|start" which is a bash script.Is this the one that you are referring to? I intend to listen on the same port but in another IP, each instance will use a different ip, so I have to change the listening ip only. regards jp ----- Original Message ---- From: Ovidiu Sas <osas(a)voipembedded.com> To: Juan Perez <jperezsip2008(a)yahoo.com> Cc: Iñaki Baz Castillo <ibc(a)aliax.net>; users(a)lists.kamailio.org Sent: Friday, April 3, 2009 3:53:25 PM Subject: Re: [Kamailio-Users] another instance of kamailio on the same machine All you need is to follow this simple steps: 1. make a clean install of kamailio 2. define your config files for each service: - kamailio1.cfg - kamailio2.cfg 3. create two seprate init scripts: kamailio1 and kamailio2 4. make sure that each init script is using the appropriate config file (use option -f <my_config file>) 5. make sure that you are not listening on the same sockets for both servers (i.e. set one server on port 506 and the second one on port 5070) 6. If you are creating pid files, make sure that the pid files are different for each service That's it. You don't need any symbolic links.

[Kamailio-Users] another instance of kamailio on the same machine
by Juan Perez 03 Apr '09

hi To install another instance of kamailio listening in another IP, does one need to do something in particular aside from install it in another directory? Also, when it is time to run the script to create the mysql tables, how can I tell the script to create a db named "openser2" to avoid deleting the existing one named by default "openser" ? Just by changing the line DBNAME=openser in kamctlrc to DBNAME=openser2? thank you jp
