Participating in an Encrypted Call
If encryption is enabled on the system, a locked padlock icon appears on the
monitor when a call is encrypted. If a call is unencrypted, an unlocked padlock
appears on the monitor.
• If you are in a point-to-point call or a multipoint call hosted by another
system, the padlock icon displays the state of your individual connection.
• If you are hosting a multipoint call, the padlock icon displays the
combined state of all connections: encrypted if all connections in the call
are encrypted, unencrypted if one or more connections in the call are not
encrypted.
In one call, some connections might be encrypted while others are not. The
padlock icon might not accurately indicate whether the call is encrypted if the
call is cascaded or includes an audio-only endpoint. If encryption is required
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.
Points to note about special dialing scenarios:
• 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 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 are prompted to save 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.
• To place a call within your PBX system, enter the internal extension instead of
the full number.
• If you need to insert a pause, add one comma in the dial string for each second
you want the system to pause.
