Polycom 6000 manual Configuring Call Preferences, Go to System Admin Settings Network IP Firewall

Administrator’s Guide for Polycom QDX 6000 Systems

∙Enable firewall traversal on the Polycom QDX 6000 system.

∙Register the Polycom QDX 6000 system to an external V2IU Traversal Server Gateway that supports the H.460.18 and H.460.19 standards.

∙Make sure that firewalls being traversed allow Polycom QDX 6000 systems behind them to open outbound TCP and UDP connections. Disable H.323-aware features on the firewall.

―Firewalls with a stricter rule set should allow Polycom QDX 6000 systems to open at least the following outbound TCP and UDP ports: 1720 (TCP), 14085-15084 (TCP) and 1719(UDP), 16386-25386 (UDP).

―Firewalls should permit inbound traffic to TCP and UDP ports that have been opened earlier in the outbound direction.

To enable firewall traversal on a Polycom QDX 6000 system:

1Go to System > Admin Settings > Network > IP > Firewall.

2Select Enable H.460 Firewall Traversal.

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:

1Go to System > Admin Settings > Network > Call Preference.

2Configure 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.264	Specifies that the system should use H.264 for video.
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.
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.
