Recent Changes• More general event name: perfrpt
– Parameters in event reflect voice quality metrics– Event can be extended for general performance reporting– Mime type also changed
• Syntax additions and clean up– More identification parameters, such as session 5-tuple, call identifier– Timestamps for start and end – allow for interval, mid-session, and end of session
reporting– More threshold types; extensions are also explicitly permitted– Enhanced readability with more descriptive parameters
• More call flows– SUBSCRIBE/NOTIFY and PUBLISH flows for both threshold and end of session
reports – Message formats for each flow
• Finalized details on use of PUBLISH and event state– Neither party maintains a soft or hard state– Intention, like other PUBLISH services, is to reduce messaging
