Step	Command	Purpose

	audio 7k-audio restricted-digital	be used for calls from the H.323 gateway to
	unrestricted-digital speech video	another gateway of the system (incoming

		tion transfer capability to be used except for
		the transparent setting, which indicates that
		the information transfer capability of the call
		should be forwarded transparently.
2	node(if- h323)[if-name]#itc tx {3k1-	Specifies the information transfer capability to
	audio 7k-audio restricted-digital	be used for calls from any gateway of the sys-
	unrestricted-digital speech video	tem to the H.323 gateway (outgoing calls).
	transparent }	All settings force the specified information
		transfer capability to be used except for the
		transparent setting, which indicates that the
		information transfer capability of the call
		should be forwarded transparently.

Example: Configure information transfer capability handling

In the following example the information transfer capability for inbound calls through the H.323 interface Myh323If is forced to speech. This is an appropriate setting, when communicating to Microsoft Netmeeting clients.

Configuring CLIP/CLIR support (optional)

According to the H.323 standard, information about calling line identification presentation/calling line identifi- cation restriction (CLIP/CLIR) is not provided, when using the H.323 protocol. However, there are H.323 equipment vendors, which allow tunneling this information through an H.323 connection. The additional information is inserted in octed 3a of the calling party number information element in the Q.931 part of the H.323 setup message.

Note This functionality is not standardized and might cause interoperability prob- lems, if enabled.

Procedure: To enable tunnelling of CLIP/CLIR information over H.323
