Microsoft Skype for Business Presence of Third-Party
Endpoints
Microsoft presence capability allows Skype for Business users to know the status (e.g.,
"Available" or "Do Not Disturb") of their contacts. Presence status of contacts is displayed on the
user's Skype for Business endpoint. Presence information of Skype for Business endpoints (such
as Skype for Business desktop client) is handled solely by the Skype for Business Server, without
any intervention of the device. However, when third-party (non-Skype for Business) endpoint
devices (e.g., mobile phone or PBX phone) are used by the Skype for Business users, presence
status information can only be reported to the Skype for Business Server by the device. For
example, if John and Alice are Skype for Business users and John makes or receives a call on a
mobile device, Alice is able to see that John is in a call, even though the call is not on a native
Skype for Business endpoint. Once the device reports the presence status, the Skype for Business
Server sends this status change to the Skype for Business users in the network.

The device notifies the Skype for Business Server of a user's presence status, by using SIP
PUBLISH messages. The message transactions between the device and Skype for Business
Server is as follows:
1. The device routes a call between two Skype for Business users and when connected, sends a
PUBLISH message with the Event header set to "presence", Expires header set to "600",
Content-Type header set to "application/pidf+xml", and where the XML body's "activity" is set
to "on-the-phone", as shown in the following example for user John Doe:
PUBLISH sip:john.doe@sfb.example SIP/2.0
From: <sip:john.doe@sfb.example>;tag=1c537837102
To: <sip:john.doe@sfb.example>
Time Count Index Call From
22:11:52 0
22:11:57 0
22:12:03 0
22:11:45 0
Currently, the device reports the following presence status:
✔
"On the Phone" - user is busy (in a call or doesn't want to be disturbed)
✔
"Clear" - cancels the "On the Phone" status (returning the user's presence to
its previous state)
The feature supports Skype for Business Server 2015 and Lync Server version
5.0.8308.866 and later.
