How Converged Desktop Services works 17

In Converged Mode, incoming and outgoing calls to and from a converged

telephone notify the MCS 5100. Upon notiﬁcation, the MCS 5100 then

provides different SIP services and features to the user. The features

include the following, depending on where the call is destined, or from

where it originated.

All calls to or from a Converged Desktop user receive:

•Call log — Allows a user to see who has called and when the call

occurred.

•Real-time call state update — Provides the presence (status) of a user.

For example,"active on the phone" or "active available".

•Presence update — Displays the status of other users if the user is

added in the Friends list. The Friends list is a list of friends/users that

were added (by the user) from the PersonalDirectory Book, Global

Directory Book, or from the call logs. This feature is provided by the

MCS 5100 to all PC Clients (including the Converged PCC). Activity on

the telephone can update the presence on the PC Client. For example,

establishing a voice call to the telephone can update your presence for

all registered MCS 5100 users to a presence update such as "Active on

the phone". Other presence updates include "Available", "Unavailable",

or "Ofﬂine".

•Popup window on the convergedPC Client — Opens a window when

receiving a call. The user sees the caller’s name and picture ID (if a

picture is available). A popup window also opens when the user calls

another Converged Desktop user or calls a stand-alone SIP user.

•Click-to-Call — Allows a user to click a contact from their PC Client and

make a call. The call is initiated from the PC Client but the call is placed

from the telephone. For more information, see "Click-to-Call" (page 25).

The following featuresare available if the call if originated on, or destined

for, a SIP client:

•Application sharing — Allows users to share applications such as

whiteboard functionality,clipboard transfers, instant messaging, and

ﬁle transfers.

•Video — Allows users to have a video conversation. The voice portion

of the conversation is provided by the telephone and the video portion

is provided by the PC Client. It is possible to add video to an already

initiated telephone conversation. If in Converged Mode, the video

can be started manually from the PC Client. The Converged Desktop

application knows from where to pick up the video because the

requested video session is bound with the voice conversation. If the

voice conversationis dropped, then the video session is automatically

closed.
