Method
Specifies the preferred method for dialing various call types. If
set to Auto, calls use the configured Dialing Order. If set to
Manual, the system prompts the user to select the call type
from a list when placing a call.

Dialing Order or the Phone Dialing Order first when placing
calls.

Order
Specifies how the system places video calls to directory
entries that have more than one type of number. It also
specifies how the system places video calls from the Place a

tries to place the call using the next call type in the list.
This setting is available only when Preferred Dialing Method
is set to Auto.
