Types of Video Calls You Can Make
Depending on your system configuration, you may be able to make calls using
H.323 or SIP.
The following table lists some possible call combinations.
Participating in an Encrypted Call
If encryption is enabled on the system, a padlock icon appears on the monitor
to indicate whether a call is encrypted or unencrypted.
From... You can call... By dialing...
LAN Networked and Public
Sites
SIP URI, E.164 address, DNS name, or
IP address.
Protected and Private
Sites
Typically, the far site's gateway number
then the number of the far-site system.
Consult with the far site about the best
method for placing the call.
ISDN Depending on the H.323 gatekeeper or
SIP server, the access code of the
near-site gateway, the speed code, and
the ISDN number of the far site. Contact
your system administrator for more
information.
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, you can save only the gateway number when
the call ends.
