Additional SIP Telephony services

Additional SIP Telephony services

  • SIP for the Hearing Impaired
  • Emergency Services
  • Precedence signaling (military, government, emergency services, …)

RFC 3487 gives the requirements for resource priority mechanisms for SIP

  • Message Waiting, Voice Mail, and Unified Messaging

See for example Interactive Intelligence’s Communité® (“ka-mune-i-tay”) http://www.inin.com/products/communite/communite.asp

  • Call Waiting
  • SIP continuing presence service
    • The I-Am-Alive (IAA) database [Tada 2000] is a distributed database system that users can query after-the-event to determine the status of a person - it does not require the session properties of SIP
    • Is there a SIP corollary - for continuing presence?
