The same logical UAS (i.e. same dialog) is not allowed to send different SDP in different responses to the INVITE.
If B and B' are separate dialogs (i.e. the to-tag in the two 183 responses are different), then they are two logical UASs and each is sending only one SDP.
cheers,

Subject: [SIPForum-discussion] Can we send 183 twice with the change in Media
Hi,
Can anyone help me on this.
Is it possible to send 183 twice with Media changed.
INVITE ---------------->
<--------------- 100 TRYING
<--------------- 183 Session Progress (Media as B)
<--------------- 183 Session Progress (Media as B' )
<--------------- 200 OK (Media as B' )
Will call be established in this case.
Thanks,
~Abhishek
