CALLING AND ANSWERING

Types of Video Calls You Can Make

You can make either ISDN or IP calls (or both) using the VSX system, depending on your system configuration. You can call systems on ISDN networks, on the same LAN as your system, or on a different LAN from your system. The network used by your system and the far-site system can affect how you dial the call.

From…	You can call…	By dialing…
ISDN	ISDN	Phone number
	IP	Phone number of the far-site gateway and
		the extension (E.164 address) of the far
		site.
		Enter the extension after the gateway
		number or wait until the gateway prompts
		you for the extension.
LAN	Same LAN	Alias, E.164 address, or IP address
	Different LAN	Access code of the near-site gateway, the
		selected speed code, the ISDN number for
		the far-site gateway, and the extension
		(E.164 address) of the far site.
		Enter the extension after the gateway
		number or wait until the gateway prompts
		you for the extension.
	ISDN	Access code of the near-site gateway, the
		selected speed code, and the ISDN number
		for the far site.

When you call an IP system through a gateway that requires an extension (E.164 address), enter the extension in the dialing field whenever possible. Check with your network administrator for the extension delimiter you will need to enter into the dialing field. For example, some networks use ## to separate the extension from the IP address.

When you include the extension, you will be given the option of saving both the number and the extension in the directory when the call ends. If you enter the extension after the gateway connects, then you can save only the gateway number when the call ends.
