26Converged Office component overview

Gateway and Services to always tandem through the user’s active Call Server. Note that with Geographic Redundancy features, a user’s active Call Server may change during failure scenarios.

The Network Class of Service (NCOS) setting for outgoing calls from Office Communicator clients is determined by the configuration of the MARP TN when in a MADN group, or by the configuration of the PCA when it is the only TN for the user.

With PCA and Remote Call Control configured, users receive one pop-up window for the incoming call to the phone or computer. Users can choose the most convenient way to answer an incoming call.

Personal Call Assistant (PCA) service

While at the office, a user may decide to use a desktop phone to answer calls. However, the user can still accept calls through the OC 2007 while they travel to locations that have network connectivity (for example,

at hotels).

The following steps correspond to the numbers in the figure:

1.The CS 1000 system receives a PSTN call to the user’s phone number.

2.The CS 1000 uses the PCA feature to provide simultaneous ringing to both the user’s phone and the Office Communicator voice client.

3.The user can answer the call through the CS 1000 phone or the Office Communicator voice client.

Users can be reached anywhere on the network and significant cost savings are incurred by using IP telephony through Virtual Private Network (VPN) access to their private network.

As part of the telephony services, many incoming call features are available even when using the OC 2007 as a telephony device or more
