Asking what the "real" objective is suggests there is a hidden reason for my question. I can assure there is no hidden reason. We're simply investigating the possible use of the Kamailio SIP server and would like to know its capabilities and which RFCs it supports. Our current SIP server supports a set of RFCs. So, it seems logical to ask what RFCs an alternative SIP Server supports. The Kamailio website uses the words "Among supported standards:" on its interoperability page. Maybe the folks at Kamailio can provide you with their meaning of the word "supported".
If you understand that SIP consists of a core RFC (3261) and hundreds of additional features and extensions specified by other drafts and RFCs, in varying stages of approval and de facto adoption, then you would be able to appreciate that this is not a black-and-white, yes-or-no question.
