The SIP transport sublayer is a layer within SIP, and therefore pertains to the application layer, where the transport layer is a full TCP/IP Layer within its own. These two layers are contiguous layer.
*chapter 7.1.2 Morgan Kauffman’s book*
Masih aga bingung, gimana susunan protokol SIP dan kaitannya ama TCP/IP (ada sublayer SIP segala). slow 
Oh, I really like to learn about this thing.
Lately, I am reading a book titled : IMS Using SIP
Why IMS ? Yeah, 2 internships I did (in different company ) were about IMS fundamentals,
My Security Paper is about IMS security,
and My FInal Project is about implementation of Open IMS
at least, I am hoping that I will get something in mind after finished reading this book 
Going to share my presentation files in this blog, probably next month..
Wish me luck for everything I am planning to do
