Configuring the Device for Skype for Business Presence

The following procedure describes how to configure the device for notifying Skype for Business
Server of presence status of Skype for Business users when making and receiving calls using
third- party, endpoint devices. To help you understand the configuration, the following lists in
chronological order the main processing steps:
1. The device receives an incoming call.
2. The device uses a Call Setup Rule to perform LDAP queries on the Microsoft Active Directory
to retrieve Skype for Business usernames (Request URIs) for the corresponding calling
(source) and/or called (destination) number. For SBC calls, the Call Setup Rule is associated
with the classified source IP Group (in the IP Groups table).
3. The device routes the call to the required destination, according to the normal routing rules.
4. When the call is connected, the device sends a SIP PUBLISH message to Skype for Business
Server, indicating that the users' presence status is now "On-the-Phone".
5. When the call ends, the device sends another SIP PUBLISH message to the Skype for
Business Server, clearing the users' "On-the-Phone" status (the presence status changes to
what it was before the call was connected).
