Greetings, RFC 3842 briefly discusses both request-uri and To. However I'm not sure how to interpret meaning of request-uri as it relates to the To header. The examples reflect the request-uri being the account (i.e. subscribe's request-uri is same as notify's message-account); however the not

You will carry Conent-Type with 0 Content-Length when you say "I am carrying 0 length XYZ Content-Type", which is different then saying "I am carrying no body with an type". Typical scenario would be INVITE without offer sdp. You still need to have Conent-Type as "application/sdp". If you remove Co
