Hi Ben,
The paragraph you refer to is this one :
o After having sent or received an answer to the first offer, the
UAC MAY generate subsequent offers in requests based on rules
specified for that method, but only if it has received answers
to any previous offers, and has not sent any offers to which it
hasn't gotten an answer.
So the 200 must contain the same SDP as the 180 because there is no SDP
replied back between the 180 and 200 ?
