Allows users to place IDSN calls.

Display IP Dialing
Extension Adds a field to the Video Phone screen so you can enter
the H.323 extension separately from the gateway ID.
If you choose not to add a field for the extension, users can
either append the extension to the gateway number or use
the Tone Pad to enter the extension when the gateway
requests it.
Allow H.320 and H.323
Mixed Calls Allows users to place and receive multipoint calls that
include both IP and ISDN sites. This choice is available
only if you allow both ISDN and LAN calls on this system.
Unchecking this option provides extra security for systems
requiring LAN connectivity while placing encrypted calls
over ISDN lines. If you clear this selection, IP endpoints
cannot join ISDN calls.

Secondary call Type
Choice
Allows you to specify how to place calls to Directory entries
containing multiple numbers. You can also specify a call
type to use when the primary call type is not available.
If you choose Manual, the system prompts the user to
choose a call type.
