I am never quite sure how come the world is so segmented. The realities of the market are far more ecclectic to me then the industry terms such as FMC, IMS, UC.

And in reality, I think that is exemplified by the UC event going on in TelAviv on November 17th that is worth your while.

Given there use of SVC for Video, integrations on IMS and their history in SIP it should be a great experience.
