Dialing and numbering plan issues for the mixed network

The converged Multimedia PC Client provides several ways for a user to
initiate Click-to-Call, including:

•

using the Directory window

•

using the Friends Online window

•

using the Call Logs window (Outbox and Inbox tabs)

•

using the Make a Call window (Dialpad, Recent, and Directory tabs)

These four user interfaces retrieve an address. The retrieved address has
several origins, including:

•

The address is an MCS 5100 username (as defined by an MCS 5100
administrator).

•

The address was delivered by an incoming call over a route.

•

The address was entered directly by the user (personal directory).

•

The address was entered by an MCS 5100 administrator or retrieved
from a directory (global directory).

It is very difficult for the CS 1000 system to route calls based on the
retrieved address alone. The address must be either:

•

explicitly qualified (in terms of phone-context) by the MCS 5100 system,
or

•

implicitly qualified (using a proper prefix) by the MCS 5100 system

Problematic Click-to-Call scenarios

Scenario 1:
Click-to-Call using an incoming call log when the call has come from a
route

In this scenario, the calling party number stored in the call log must

be explicitly or implicitly qualified. The MCS 5100 system must store the
original phone-context in the call log.

Scenario 2:
Click-to-Call using a directory entry (Call at...)

In this scenario, the

number stored in the directory entry must include the proper prefix.

The problem arises because directory entries are created by users
themselves (PA, Contact Info), MCS 5100 system administrators, or an
external Directory Service (such as the Nortel Global Directory). Directory
entries may not include the required access codes.

Users must be warned to ensure that all directory entries they intend to use
include correct access codes. An MCS 5100 or CD user may edit their
personal directory through the PA.
