Office Communicator-initiated Call Transfer in Computer and PBX
Integration Enabled
If the Office Communicator transfers a call, the SIP
stack of the CS 1000 must handle the request to transfer the call. As such,
the number a user is transferred to is not subject to the Class of Service

the transfer). The Class of Service and Call Restriction that control the
transfer is that of the SIP trunk itself.

required for each customer. Each customer configured on the Call Server
requires a separate node number and domain. For more information about

Office Communicator Mobile
Converged Office requires the client to
support Telephony Gateway. The Mobile version of Office Communicator,
called Office Communicator Mobile (COMO), has limited support for
