Hi,
There is nothing like two callids, It is a unique identifier for the
call-leg/session. Hence it should match with the request callid.

Thanks for your response!
I understand call-Id should be unique for one call and 4xx should be proper
response. Does any sip rfc mention what ideally we should do if we get two
different call-id.
