Hello,

First of all, thanks for taking a look.

I once had this problem in my college lab, but at that time other softphones 
were also not able to register. So, I felt that the network admins have blocked 
the ports or something like that. Could it be because of a firewall? Below is 
stripped version of how I try to register, do I seem to be doing something 
awefully wrong?

Thank you, I will try this out.

Hitesh
