Calling Through Gateways

On certain occasions, you may need to videoconference with parties who are
connected to different networks or telephone exchanges. As noted earlier in this
User's Guide, you can directly call any ISDN number, if you dial the correct
telephony prefixes (long distance code, country code, area code, etc.).
You can also call a system that is outside of your LAN. When you dial a remote IP
address, the router that you designate as your default gateway (see "LAN
Connection and Registration" on page 4-4) takes the call and routes it to the
destination.
However, at some point, you may be unable to take advantage of one of the
communication modes (IP or ISDN). If this happens, you can still meet with your
contacts by calling through an H.323/H.320 (IP/ISDN) Gateway.
q
If your LAN connection is down, you can call the Gateway through your ISDN
lines and reach H.323 systems (IP addresses and other LAN-based addresses).
q
If your ISDN lines are down, you can call the Gateway through your LAN
connection and reach H.320 systems (ISDN numbers).
