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,
ALEX

RFC 3665 would be sufficient.
