looking for a valuable project in VOIP / IMS

hi all,
I am a senior undergraduate in Indian Institute of Technology, Roorkee.
As a part of our course structure, I have to do a Final year project in
the last two semesters. I have planned to do my B.Tech Project in the
field of Voice over IP (VoIP) and most probably related to IMS
networks. But i am unable to think of a nice project that has some
value in today's IT industry or which may come out to be a very good
research project. So, I will be very thankful to you if you can help me
in this regard or else if i could be a part of any on going project in
some company/university.

Thanks

Regards
