3. Select and configure these settings on the Network Dialing screen:

Setting Description

Basic Mode Enables a limited operating mode that uses H.261 for

video and G.711 for audio. This mode provides

administrators with a workaround for interoperability

issues that cannot be solved using other methods.

The Basic Mode setting stays in effect until you

change it.

Basic Mode disables many system features such as

content sharing, far end camera control, and

advanced audio and video algorithms. Use Basic

Mode only when calling systems that fail to operate

properly with these advanced features.

IP H.323 Allows the system to make IP calls.

SIP Allows the system to use SIP when connecting IP

calls.

H.264 Specifies that the system should use H.264 for video.

H.239 Specifies standards-based People+Content data

collaboration. Enable this option if you know that

H.239 is supported by the far sites you will call. If

callers experience issues when sharing content with

other Polycom systems, disable this setting.

H.264 Content If this option is enabled, the endpoint will use H.264

protocol firstly when it is sending content. Some

endpoints have the content which is not compatible

with H.264, enabling this option may disable the

content feature. In this case, it is recommended to

disable this option.

ISDN Gateway Allows users to place IP-to-ISDN calls through a

gateway.
