Do you mean *uppercase* here ?? 

RFC 3261 - 25.1 Basic Rules - 

Request-Line  =  Method SP Request-URI SP SIP-Version CRLF
Status-Line  =  SIP-Version SP Status-Code SP Reason-Phrase CRLF

SIP-Version    =  "SIP" "/" 1*DIGIT "." 1*DIGIT

Yes, RFC 3261 says that devices must use upper-case for SIP version
field. But as per BNF grammar in RC 3261, they MUST accept lowercase.
