• RFC 3842 message counts are expressed per message class as new/old pairs with optional urgent new/old counts in parentheses, e.g. 'Voice-Message: 2/8 (0/2)'. in context
• RFC 3842 sets the default subscription duration for the message-summary event package to one hour. in context
• RFC 3842 defines the SIP event package 'message-summary' for message waiting indication, carried in the body type application/simple-message-summary. in context
• In an RFC 3842 message summary, the Messages-Waiting line carries yes or no to indicate whether messages are waiting. in context
• RFC 3842 describes message-summary notifications within a SUBSCRIBE-established subscription and does not appear to define an unsolicited (subscription-less) NOTIFY mode; vendor 'unsolicited NOTIFY' MWI is therefore a vendor practice rather than something RFC 3842 specifies. inferred in context
