Abstract: "Third party call control refers to the ability of one entity to
create a call in which communications is actually between other
parties."  Communication, probably, not communications.

Introduction:"  Third party call control (referred to as 3pcc) is 
often used for operator
services (where an operator creates a call that connects two
participants together), and conferencing."  Is this comma needed?

In section 4.4 "whether their is compatible" should be "whether there is
compatible".

B2BUA is used without expansion.
