[SR-Users] Reg : Kamailio and jitsi with Audio Call Doubts

Hi, Actually my doubt is whether jitsi will support to make a call over the internet? I like to explain what i have done and what i need help from you . Steps to make jitsi client to work with kamailio. 1. I have installed kamailio server in my linux box, created global ip to my local ip and i have installed jitsi client in my machine and my friend machine. 2. Then i registered my SIP accounts with the local ip address like below 3. Then i added contacts of my friends. All my friends are in online. I could make audio call and speak with each other with local network. In this case no problem. 4. But the problem is when i use public ip instead of local ip in account registration wizard, it is showing all my friends are in offline eventhough they are in online. Actually my requirements is , I want to make audio call over internet(i.e from other domain). I really stuck in this case. Please help me how to achieve this? Advance Thanks, Balakrishnan.N
