Configuring Call Preferences
Call preferences help you manage the network bandwidth used for calls. You
can specify the default and optional call settings for outgoing calls. You can
also limit the call speeds of incoming calls.
To choose call preferences:
1. Go to System > Admin Settings > Network > Call Preference.
2. Configure these settings on the Call Preference 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.
H.239 Specifies standards-based People+Content data collaboration.
Select 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.
IP H.323 Allows the system to make IP calls.
SIP Allows the system to use SIP when connecting IP calls.
Analog Phone Allows the system to make voice-only calls to any phone using
an analog phone line.
Transcoding Specifies whether the system allows each far-site system to
connect at the best possible call rate and audio/video
algorithm. If transcoding is disabled, the Polycom HDX system
down-speeds all connections to the same call rate.

through a gateway.
