Security Level Select the security level that you want to assign to the
Remote Gateway 9150 unit according to the following
table:
Field Description
Level Description
No Security When set to security level 1, the
Remote Gateway 9150 permits all
incoming calls regardless of
source.
Note: No security is the default
security level.
Caller ID When you select Caller ID, you can
define the valid Caller IDs that the
Remote Gateway 9150 can
receive. If the Caller ID on the
incoming call matches what is
configured on the remote unit, the
connection is established. If it does
not match, the RLC drops the call.
Note: Caller ID authentication
cannot be performed over the IP
network. Caller ID authentication
can be used only on the PSTN.
Provision ID If you select Provision ID, security
identifiers must be configured on
both the Remote Gateway 9150
and the RLC port that the unit is
assigned to. When a connection to
or from the host PBX is attempted,
the security identifiers are
compared. If they match, the
connection is established. If they
do not match, the call is dropped.
