Figure 10: Steps for changing presence information



  • The protocol clients are signed in, as described in section 2.5.5.


  1. When a user’s presence information changes, the user’s protocol client (Client A) sends a SIP SERVICE request to the user’s home server. The SIP SERVICE request contains one or more of the following:

    • The user’s calendar and meetings obtained from Microsoft Exchange Server.

    • The device on which the protocol client is running and the device’s capabilities.

    • The user’s activity on a particular device.

    • The user’s contact information, such as phone numbers, office location, and title.

  2. The server responds with a 200 OK message, which contains the user’s updated presence information.

  3. The server sends a SIP NOTIFY request to all other protocol clients (for example, Client B) that subscribe to the user’s presence information, as described in [MS-PRES].


  • The user’s presence state has been changed and this change has been communicated to the protocol clients that have subscribed to the user’s presence information.
