Polycom Audio and Video manual To configure H.323 settings

Administrator’s Guide for the V500 System

To configure H.323 settings:

1.Go to System > Admin Settings > Network > IP > H.323 Settings.

2.Configure these settings:

Setting	Description
Enable IP H.323	Check this to allow IP dialing.
Display H.323	Check this if you want to place gateway calls by entering the H.323
Extension	extension separately from the gateway ID.
	If you do not check this box, you can make gateway calls by
	entering the call information in this format:
	gateway ID + TCS4 delimiter + extension
	To determine your TCS4 delimiter, ask with your network provider.
H.323 Name	This is the name that gatekeepers and gateways can use to
	identify this system. You can make point-to-point calls using H.323
	names if both systems are registered to a gatekeeper.
	The H.323 Name is the same as the System Name, unless you
	change it. Your dial plan may define the names you can use.
H.323 Extension	You can place point-to-point calls using the extension if both
(E.164)	systems are registered with a gatekeeper.
	The default H.323 Extension is based on the system serial
	number, but you can change it. Your dial plan may define the
	extensions you can use.

3.If you have a gatekeeper, select and configure these settings:

Setting	Description
Use Gatekeeper	Select one of the following, but keep in mind that gateways and
	gatekeepers are required for calls between ISDN and IP networks:
	• Off — Calls do not use a gatekeeper.
	• Auto — System automatically finds an available gatekeeper.
	• Specify — Calls use the specified gatekeeper. Enter the
	gatekeeper’s IP address or name (for example,
	gatekeeper.companyname.usa.com or 255.255.255.255).
H.323 Name	This is the name that gatekeepers and gateways use to identify
	this system. You can make point-to-point calls using H.323 names
	if both systems are registered to a gatekeeper.
	The H.323 Name is the same as the System Name, unless you
	change it. Your dial plan may define the names you can use.
H.323 Extension	You can place point-to-point calls using the extension if both
(E.164)	systems are registered with a gatekeeper.
	The default H.323 Extension is based on the system serial
	number, but you can change it. Your dial plan may define the
	extensions you can use.
