Hi Sergey, Thanks very much for your reply. We are able to install the kamailio and kamailio IMS packages. I will create the ticket so that it will be helpful for others as well. We are able to start the kamailio services with default configuration file, but as soon as we edit the /etc/kamailio/kamailio.cfg file we are getting this error as shown in the enclosed image. I have just modified the listen IP address , port only . Can you help me guide what are the possible reasons for this reason ?

Can you guys help me share any document/wiki which is helpful for my cause ? I will be really grateful if someone can reply me by today.
