incoming call stops being encrypted for some reason; the outgoing part of the call
will also drop the encryption and both callers will know that the call is no longer
encrypted.
Select
Required
in the appropriate checkbox(es) if you always want the IP and/or
ISDN part of a call to be encrypted or
Optional
if encryption is only to be used to
endpoints that support it. Note that:
Encryption must also be enabled globally in the
Settings > Encryption
page.
If
Required
is selected and the endpoint does not support encryption, the
call will be disconnected. If the endpoint does support encryption, no
media is passed until encryption can be ensured. However if you select
Optional
and the endpoint supports encryption, then a call to may start
even before encryption can be guaranteed but will use encryption as
soon as possible
If the
Call type
is

Place call on

7. For
Codecs allowed
select an option from the drop-down list: <use default choices>, Custom
codec choices or Safe codec choices. The last two options are provided for older endpoints that
you cannot connect to when some codecs are enabled (even if the endpoint supports those
codecs). We recommend that you only use these options when you experience a problem.
o
When you select Custom codec choices, the screen refreshes and you can select the
audio, video and H.239 video codecs that are allowed with this dial plan
o
Safe codec choices only allows G711 and H261
