>From is the logical address (AOR) - Eg: mohan at sip.net

Contact is the original address (FQDN)  - Eg: mohan at 10.20.30.4

Regards,

Mohan.

Then what is the difference between >From and Contact?

Both denote the same "sender"?

	To and Contact is entirely different

	To header is logical address of *receiver*.
	Contact header is real address of  *sender*  who send the SIP
message.

		Hi,

		If To header field denotes the destination address then
please explain me the difference of To header field and Contact header
field.

			To header is always the final destination in a
point to point call.

			But, Request URI may or may not change with each
hop depending on the routing used.(loose routing or strict routing.

			If loose routing is used , then Request URI is
same as the value of 'To'

			If strict routing is used, Request URI changes
with each hop.

			Please refer to rfc 3261 for more details.

			Hope this is clear.

			Regards,

			Murgesh

			Can anybody explain the difference between the
usages of the To Header
			and the Request-URI in the start line? They both
specify the destination
			of the invite message, but which is used to the
real routing purpose?
			And how the rest is used?

			Thanks,

			RFC 3665 would be sufficient.
