Configuring the security level
Introduction
It is recommended that you implement a security authentication method on both
the MIG RLC and the Remote Office 9150 unit to prevent toll fraud.
The security level defines what type of security authentication is used between
the Remote Office 9150 unit and the host PBX. The information used to perform
security authentication depends on the security level chosen.
No security
When no security is being used, the MIG RLC and Remote Office 9150 unit do
not perform a security check. All connection attempts to the host PBX and
Remote Office 9150 unit are allowed.
Caller ID
When you select Caller ID, you can define the valid Caller IDs that the Remote
Office 9150 unit can receive. If the Caller ID on the incoming call matches what
is configured on the Remote Office 9150 unit, the connection is established. If it
does not match, the call is dropped.
Note: Caller ID cannot be performed over the IP network. Caller ID
authentication can be used only on the circuit-switched network.
Security identifier
You can use security identifier authentication over the IP or circuit-switched
network. If you select this security level, security identifiers must be configured
on both the Remote Office 9150 unit and the MIG RLC port to which the unit is
assigned. 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.
