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.

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.
