Hi Daniel/ Sammy , I made the changes in config as suggested (i.e. move the define variables at the top of the file rather then in the middle) Regarding setting debug=3 => I am setting WITH_DEBUG in the config file so based on processing of this symbol I believe debug=4 is set.# For the log facility in the kamailio.cfg I have set the option log_facility=LOG_LOCAL1 & in my syslog.cfg (attached again) I have set the following local1.* -/var/log/kamailio but still I dont see any logs in this location when I start kamailio I can see the kamailio process - (in total there are 19 processes here is the root process all other are child processes of this process) kamailio 3375 1 0 08:06 ? 00:00:00 /usr/local/sbin/kamailio -P /var/run/kamailio.pid -m 32 -M 4 -u kamailio -g kamailio I can also see kamailio starting to listen on port 5060 port on the local machine on both UDP & TCP interfaces I am using an xlite phone on windows to attempt to register - on my Kamailio VM (using UDP) I started a tcpdump to see if I am receiving the Register messages - I can see the register packets coming to the Kamailio hosts from the phone - but I dont see any responses from Kamailio. Also as there are no logs I dont know what is going wrong. Regards, Faisal On Tue, May 29, 2012 at 2:37 PM, SamyGo <govoiper(a)gmail.com> wrote:

Hi Faisal, You say you added to syslog.conf: local1.* -/var/log/kamailio Is that exactly how it appears? If so, I think you need to remove the hyphen so it becomes: local1.* /var/log/kamailio As Sammy said, don't forget to restart syslog.

[netstat -pln|grep kamailio] 3- Verify if your kamailio is using the same protocol as of your client i.e TCP or UDP or TLS etc. 4- instead of viewing the file /var/log/kamailio see /var/log/messages because you haven't mentioned local7 as Log facility in your config. I don't see your syslog.conf file in this mail! check that file and follow the referenced link completely. Also see your configurations kamailio.cfg file and use define tags from second line from top onward i.e just after #!KAMAILIO. Try getting rid of the comment line "####### Defined Values #########" - in my experience such comment before define cause trouble with configurations. See all these and then reply with updates.

Change the L_WARN to L_NOTICE that makes a difference when you've different debug=x value. and yes you are right about the "-" in -/var/log/kamailio , it is really required to prevent kamailio from waiting on syslog to print lines and then continue.

Hi Daniel, Many thanks - local firewall it is my bad - I thought the fact packet sniffer can see the packet - there is no network firewall blocking the packet - but there was an IP-Tables on the host - I shutdown the ip-tables & now the registration is going through & I am also able to send calls between subscribers . The log_stderror=yes is working now I can get the error messages on the console (but for that I have to start kamailio by typing kamailio - when I start using service kamailio start I dont get any log messages). Thanks its a step forward - I will review the config again for syslog configuration as for troubleshooting its better to have the logs dumped to a file rather then on std_error. BTW: If you can point me to some good tutorials regarding load-balancer(dispatcher module) it will be great - Regards, Faisal On Tue, May 29, 2012 at 5:32 PM, Daniel-Constantin Mierla &lt;miconda(a)gmail.com > Hello, > > I could not spot if you checked for presence of a firewall.
