Types of Video Calls You Can Make
Depending on the V500 system model you purchased, you may be able to
make either ISDN or IP calls (or both). The following table lists all possible call
combinations.
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 in the Extension field,
after the gateway number, or wait until the
gateway prompts you for the extension
and then use the remote to enter it.
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 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 and then use the
remote to enter it.
LAN
ISDN Access code of the near site’s gateway, the
selected speed code, and the ISDN number
of 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 service provider 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.
