Hi,

Whatever we call it, I think we need to have a common understanding what
we mean by terms like "session". Until now it hasn't maybe been that
important, but due to the introduction of dialog usage I think it will
become more important what terms we use.

For example, the text says that the session is terminated by a BYE. That
is fine if a session MUST always be an invite dialog usage, and nothing
else.

Regards,

Christer

Apologies for my delay in replying.

The text at the start of Section 4 says this:

  "Note that a successful REFER transaction does not terminate the
session between the
   Transferor and the Transferee.  If those parties wish to terminate
   their session, they must do so with a subsequent BYE request."

Transfer is an application on top of SIP, and as such, I think it is OK
to use terminology like "session" which has application significance
instead of "dialog" which just has SIP significance.  If others feel
that dialog is clearer here, we can change it, but I prefer session.

Thanks,
Alan
