8.3.3.5.3 SAS Routing Based on SAS Routing Table
SAS routing based on rules configured in the SAS Routing table is applicable for SAS in
the following states:
SAS in normal state, if the SASSurvivabilityMode parameter is set to 4
SAS in emergency state, if the SASSurvivabilityMode parameter is not set to 4
The SAS routing rule destination can be an IP Group, IP address, Request-URI, or ENUM
query.
For a detailed description of the SAS Routing table, see ''Configuring IP2IP Routing Table
(SAS)'' on page 163.
8.3.3.5.4 Blocking Calls from Unregistered SAS Users
To prevent malicious calls (for example, Service Theft), it is recommended to configure the
feature for blocking SIP INVITE messages received from SAS users that are not registered
in the SAS database. This applies to SAS in normal and emergency states.
To block calls from unregistered SAS users:
1. Open the 'SAS Configuration' page (Configuration tab > VoIP menu > SAS Stand
Alone Survivability).
2. From the 'SAS Block Unregistered Users' drop-down list, select 'Block'.
