Figure 35-8: Manipulating User Part in Incoming REGISTER
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 or the CLI command,
configure voip > sas sasregistrationmanipulation.
35.5.2 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.
For example, in SAS emergency state, assume an incoming INVITE has a destination
number "7001234" which is destined to a user registered in the SAS database as
"552155551234". In this scenario, the received destination number needs to be
manipulated to the number "552155551234". The outgoing INVITE sent by the device then
also contains this number in the Request-URI user part.
In normal state, the numbers are not manipulated. In this state, SAS searches the number
552155551234 in its database and if found, it sends the INVITE containing this number to
the UA.
