24 Converged Office component overview
With this solution, you can configure Personal Call Assistant (PCA) on the
CS 1000 for each user with this functionality. The CS 1000 configured with
the PCA provides number plan translations, Call Detail Recording (CDR)
for outgoing calls, and enables telephony features, such as Call forward
No Answer to Voice Mail, Attendant Recall, and participation as a client
in a Group Call for incoming calls.
With the Telephony Gateway and Services component, you can configure
the OC 2007 as a Multiple Appearance Directory Number (MADN) member
for users with PCA on the CS 1000. With PCA , calls to a user’s phone
number can be presented to both the desktop phone and to the OC 2007
client simultaneously. The user can then choose to answer on the most
convenient device.
The ability to connect between computers and phones is not natively
provided by Office Communications Server 2007; however, the Telephony
Gateway and Services component enables this functionality using the SIP
Gateway and Multimedia Convergence Manager (MCM) application. MCM
directs calls from an Office Communicator user to the CS 1000 connected
to their twinned telephone. Telephony Gateway and Services allows you
to originate and receive SIP calls (for example, VoIP and Computer calls)
from Office Communicator.
In Figure 6 "Dual forking example" (page 25) , OCS Front End (FE) forks
the call to the CS 1000. The twin phone rings once and does not send
another invite. The same scenario applies to calls originating from the
CS 1000, the OCS does not get informed to perform another fork. A new
setting is introduced on OCS 2007 server that enables or disables dual
forking for each user. Remote Call Control (SIP CTI) is available when dual
forking is enabled.
