The SIP message manipulation feature supports the following:

Manipulation on SIP message type (Method, Request/Response, and Response type)

Addition of new SIP headers

Removal of SIP headers ("black list")

Modification of SIP header components such as values, header values (e.g., URI
value of the P-Asserted-Identity header can be copied to the From header), call's
parameter values

Deletion of SIP body (e.g., if a message body is not supported at the destination
network this body is removed)

Translating one SIP response code to another

Topology hiding (generally present in SIP headers such as Via, Record Route, Route
and Service-Route).

Configurable identity hiding (information related to identity of subscribers, for example,
P-Asserted-Identity, Referred-By, Identity and Identity-Info)

Apply conditions per rule - the condition can be on parts of the message or call's
parameters

Multiple manipulation rules on the same SIP message

Multiple manipulation rules using the same condition. The following figure shows a
configuration example where rules 1 and 2 ('Row Rule' configured to Use Previous
Condition) use the condition configured for rule 0 ('Row Rule' configured to Use
Current Condition). For more information, see the description of the 'Row Rule'
parameter in this section.
