call setup failure when 200 OK (UPDATE) is sent without SDP

What steps will reproduce the problem?
0. Both caller and callee supports 100rel.
1. Callee UA sends an UPDATE *with* SDP during call setup
2. Caller UA (Boghe/Doubango) responds with 200 OK *without* SDP
3. IMS system sends BYE due to "Session realeased - Invalid SDP offer or answer"

What is the expected output? What do you see instead?
The client should respond with 200 OK *with* SDP

What version of the product are you using? On what operating system?
boghe-r75 and doubango-r666 on Windows XP/Vista/7

Please provide any additional information below.
See RFC 3311.
