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 Phone number ISDN
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.
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.
LAN
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.
