Whether the MCU is able to use encryption or
not.
When encryption status is Enabled, the MCU
advertises itself as being able to use encryption
and will use encryption if required to do so by an
endpoint. If this setting is Enabled, you can enable
or disable the use of encryption on a per-
conference basis.
If this setting is Disabled, no conference will be
able to use encryption.
The default encryption setting for new scheduled
conferences (on the >
page).
When you (or another user) create a new
conference (by choosing and clicking
), you can set the encryption
setting for the conference to be either Allowed or
Required. This control defines which option is
selected by default. However, when creating a
conference this can be changed.
When enabled, this setting forces encryption to
be used for new ad hoc conferences.
Changing this setting will have no effect on
currently active ad hoc conferences; however,
when an ad hoc conference is running, whether
or not encryption is required for that conference
can be configured (go to , select the
conference you require and select the
tab).
Select the setting for media encryption for SIP
calls:
All transports: If encryption is used for a
call, the media will be encrypted using
SRTP regardless of transport mechanism
used for call control messages.
Secure transports (TLS) only: If encryption
is used for a call, the media will only be
encrypted in calls that are set up using
TLS.
Disabled: SRTP will not be used for any
calls. The MCU will not encrypt media
for SIP calls.
For more information refer to Using encryption
with SIP, below.
When disabled, the MCU will not advertise that
it is able to encrypt using SRTP. It is only
necessary to disable SRTP if it is causing
problems.
