15.9.2 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, 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).
