Configuring Video Call Preferences

Go to System Info > Admin Setup > Video Network > Call Preferences.

Configure these settings:

If you enabled both ISDN and IP calling, select Next and configure these 
settings:

ISDN Video Calls (H.320)
(Quad BRI or PRI)

V.35 Video Calls
(V.35/RS-449/RS-530)

Allows users to place IDSN calls.

Allows users to place V.35 calls.

LAN/Internet Calls (H.323)

Allows users to place IP 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.

Primary Call Type Choice

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.
