hi iam pursuing masters in U.K i need some of the new projects in voip or ip telephony
I’m brainstorming on my final year project title on application development that is interesting to be explore in my project.

Can anyone kindly proposed some potential application development or research title that might help me get some inspiration on my project direction.

I am emphasizing on the application/information systems capabilities in our daily life/business environment.

Thank u
