❑
Using the Global Address Book . The user establishes the first
call, adds a second, and maybe a third call using the Global
Address Book. If the selected entry is a OneDial number, make
sure the Primary Call Type Choice option on the Advanced
Address Book Preferences
screen (Admin Setup > LAN/H.323
> Global Address > Preferences > Advanced Preferences ) is
configured to be Manual. Every time an additional call is
added, the user is prompted with the message “dialing IP or
ISDN”. If the selected entry is not a OneDial number, the
Primary Call Type
does not affect how calls are made. For more
information about how to place this type of call, refer to Using
the Address Book, on page 191 .
❑
Using a combination of Manual Dialer and Global Address
Book
. Establish the first call, then add a second and a third call
using the Manual Dialer and the Global Address Book. For more
information about how to place this type of call, refer to
Using
the Manual Dialer and the Address Book, on page 191 .
❑
Through Dial-In Calling . A mixed protocol call can also be
created if the user is already in a point-to-point call (IP or ISDN)
and the user receives an incoming call that uses the other
protocol (IP or ISDN). For more information about the Dial-In
Calling feature, refer to the following section
Dial-In Calling
(Optional), on page 205 .
