Yes. The 200 OK (or the 180 if using 100rel) MUST have the answer.

Subject: [Sip-implementors] Offer/Answer question

For an INVITE carrying an offer, does the offer/answer has to complete
within the INVITE transaction? Can it complete outside the transaction
but within the same dialog? Call flow is:

-------------->Invite ( offer )
<------------180 ( ringing )
<------------200OK ( empty..no offer )
------------->ACK
<------------Re-Invite ( Answer to offer in first invite )
-------------->200OK
<--------------ACK
