The CSeq is not the same since the registration renewal is a new
request. Since this is a new request within the same call leg, the cseq
should montonically increment from the one in the previous register
request.
This should answer your 2nd question as well in that the CSeq is what
determines that this is a renewal request versus being a new request.

	Hello,
	 
	I have a query regarding refreshing the existing registration. 
	 
	I suppose the Call-Id of the renewal (REGISTER) request remains
the same, but does the CSeq remain the same as that of the original
(existing) registration? 
	 
	If it does not remain the same, what is the difference between a
new registration from the same UA and renewal of an existing
registration for that UA?
	 
	Thanks in advance,
	Radhika.
