SIP+ was a proposal by Level3 on how to extend SIP to interconnect two MGCs. This functionality is now being provided by various orthogonal SIP extensions, including the carriage of multipart MIME types, the INFO method and others. These are being documented in a BCP draft. The name SIP+ is obsolete and should not be used to avoid confusion.
