Technical Summary This document specifies a way to create subscription to a list of resources in SIP. This is achieved by including the list of resources in the body of a SUBSCRIBE. Instead of having a subscriber send a SUBSCRIBE for each resource individually, the subscriber defines the resource list, subscribes to it, and gets notifications about changes in the resources' state using a single SUBSCRIBE dialog. Working Group Summary The document was originally produced by the SIPPING working group, but was transferred to the SIP working group due to the need to define a new option tag, in conformance with RFC 3427. There is consensus in the WG to publish this document. Document Quality There is a strong requirement from OMA for a SIP solution in this area. Personnel Keith Drage is the document shepherd for this document. Cullen Jennings is the responsible Area Director.
