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.
