Consider the following scenario:
You configure a Conference Auto Attendant (CAA) access number on a Microsoft Lync Server 2010 server.
A Lync 2010 user calls the CAA access number.
The user enters a conference ID.
In this scenario, the CAA cannot transfer the user to the conference. Additionally, you receive the following error message in the trace file:
The owner of the object passed does not match the original owner.
This issue occurs because a race condition occurs when the conference attendee communicate with the focus component to join the conference.
To resolve this issue, install the following cumulative update:
2670540 Description of the cumulative update for Lync Server 2010, Conferencing Attendant: February 2012
