RFC3261 20.32 Require The Require header field is used by UACs to tell UASs about options that the UAC expects the UAS to support in order to process the request.
RFC4028 8.1. Processing of Requests the proxy MAY insert a Require header field with the value 'timer' into the request. Is a SIP proxy allowed to insert Option tags when forwarding a request? In that case, why "Require" is preferred than "Supported" in RFC4028?
