Our implementation is clearing the call on receiving no SDP (answer) in 200 OK

I am not able to find any normative RFC references to support this. Can you

Alok/Srinivas,
Agree

Hi Vivek,
Here the issue is media is not in sync. If UAS is not providing the SDP in
answer, how UAC can ensure whether the ongoing media is reliable anymore
and if the session is not reliable, it should not be continued.

Hi
I tend to agree with Alok and Srinivas, I would not have cleared the dialog if
it was any other failure like a 488 response. However, here the UAS has not
sent any SDP in 200 OK. Still trying to find definitive references in RFCs.

Hi Vivek,
RFC 3264 says, if Re-INVITE fails (Ex : 4xx or 5xx any other error) UAC should
switch back to the state which has before sending the Re-INVITE.
Here Re-INVITE is not failing, it has 200 OK but no media. So UAC has no other
option so terminating the call with BYE.

Hi all,
Just thinking widely if it's violating the SDP offer/answer in ReINVITE,
then why to terminate the complete dialog instead of clearing only specific
transaction...

Hi Tarun,
IMO, this behavior is correct as it violates the offer-answer model. The
answer must have overlapped SDP. But in mentioned scenario, the media at
UAC and UAS is not in sync and therefore UAC should terminate the dialog in
such scenario.
