Conference Factory (Multiway™)
The Conference Factory application configuration is NOT replicated across a cluster.
The Conference Factory template MUST be DIFFERENT on each of the VCS peers.
When configuring a cluster to support Multiway:
1. Set up the same Conference Factory alias (the alias called by the endpoint to initiate a Multiway
conference) on each peer.
2. Set up a different Conference Factory template on each peer (so that each peer generates
unique Multiway conference IDs).
For example, if the MCU service prefix for ad hoc conferences is 775 then the Master VCS may have
a template of 775001%%@domain, peer 2 a template of 775002%%@domain, and peer 3 a
template of 775003%%@domain. In this way whichever VCS serves the conference ID, it cannot
serve a conference ID that any other VCS could have served.
a template of 775001%%@domain, peer 2 a template of 775002%%@domain, and peer 3 a
template of 775003%%@domain. In this way whichever VCS serves the conference ID, it cannot
serve a conference ID that any other VCS could have served.
The same applies across a network. If there is more than one VCS or VCS cluster that provides
Conference Factory functionality in a network, each and every VCS must provide values in a unique
range, so that no two VCSs can serve the same conference ID.

For OCS, see Microsoft OCS 2007, Lync 2010 and VCS deployment guide.
If the VCS cluster is an “OCS/Lync gateway” VCS cluster and the Microsoft OCS/Lync B2BUA is
turned off, and OCS Relay is used, some parameters on the VCS cluster, such as:
