Rfc 3261 section 20.5 says :- "All methods, including ACK and CANCEL, understood by the UA MUST be included in the list of methods in the Allow header field, when present."
My question whether REGISTER Method is to be added in Allow header field or not? Because REGISTER is also one of the sip methods. Since REGISTER is one of the necessary operations we don't add it?
