Feature Operation Description
Office Communications
Server and MCS
coexistence
ATTENTION
All Converged Office users must have their extension configured as
CLS CDMR.
A user cannot have both Office Communications Server and MCS
enabled for their extension (all TN’s that have a particular number
and extension). If any of the TN’s have CLS CDMV or CLS CDMO
configured, the extension is treated as having MCS enabled. When
MCS (SIP CD) is enabled on an extension, Office Communications
Server Converged Office is not supported for that extension in Release
4.5B and 5.0.
CallPilot
configuration For PBX Integration Enabled (Computer Mode) calls to access the
CallPilot mailbox, the Pound key (#) is pressed. Every mailbox must
have the optional messaging network configured. In a normal CS 1000
- CallPilot scenario, this configuration is optional. For PBX Integration
Enabled (Computer Mode) calls to CallPilot to work properly, this extra
configuration is required. For more information about the configuration of
CallPilot, see CallPilot Network Planning Guide (NN44200-201).
Conference Call and
Do Not Disturb (DND)
features Conference Call and DND features in RCC mode are not supported by
Microsoft.
LCS 2005 and OCS 2007 coexistence
This section describes the coexistence limitations of LCS 2005 and OCS
2007.
Client considerations
Features hosted on Office Communications Server 2007 are not supported
by the OC 2005 client. After a user is configured for enhanced presence, the
account can no longer use previous versions of OC 2005 , Communicator
Web Access 2005, or Communicator Mobile 2005. Microsoft recommends
that you upgrade all client computers for a particular user at the same time.
Communicator 2007 clients cannot log on to Live Communications Server
2005. Verify that any user whose client is upgraded to Communicator 2007
is already provisioned on an Office Communications Server.
Converged Office functionality
An upgrade from the LCS Application Proxy to the OCS Proxy Server and
MCS 2.0 to MCM 3.0 is required to manage CS 1000 telephones by the
OC 2007 client in either VOIP or RCC mode. Inter-working of MCM 2.0
with OCS Proxy Server or MCM 3.0 with LCS Application Proxy is not a
