User's Manual 31. SAS Configuration
The procedure below describes how to configure the above manipulation example.

To manipulate incoming Request-URI user part of REGISTER message:
1. Open the SAS Configuration page ( Configuration tab > VoIP menu > SAS > Stand
Alone Survivability ).
2. Under the SAS Registration Manipulation group, in the 'Leave From Right' field,
enter the number of digits (e.g., "4") to leave from the right side of the user part. This
field defines the number of digits to retain from the right side of the user part; all other
digits in the user part are removed.

3. Click Submit .
Notes:
•
The device first does manipulation according to the Remove From Right
parameter and only then according to the Leave From Right parameter.
•
Only one manipulation rule can be configured.
•
You can also configure SAS registration manipulation using the table ini
file parameter, SASRegistrationManipulation.
31.5.2 Manipulating Destination Number of Incoming INVITE
You can define a manipulation rule to manipulate the destination number in the Request-
URI of incoming INVITE messages when SAS is in emergency state. This is required, for
example, if the call is destined to a registered user but the destination number in the
received INVITE is not the number assigned to the registered user in the SAS registration
database. To overcome this and successfully route the call, you can define manipulation
rules to change the INVITE's destination number so that it matches that of the registered
user in the database. This is done using the IP to IP Inbound Manipulation table.
