The figure below illustrates a SIP message manipulation example:
Notes:
•
For a detailed description of the syntax used for configuring Message Manipulation
rules, refer to the SIP Message Manipulations Quick Reference Guide.
•
For the SBC application, Inbound message manipulation is done only after the
Classification, inbound/outbound number manipulations, and routing processes.
•
Each message can be manipulated twice - on the source leg and on the
destination leg (i.e., source and destination IP Groups).
•
Unknown SIP parts can only be added or removed.
•
SIP manipulations do not allow you to remove or add mandatory SIP headers.
They can only be modified and only on requests that initiate new dialogs.
Mandatory SIP headers include To, From, Via, CSeq, Call-Id, and Max-Forwards.
The following procedure describes how to configure Message Manipulation rules in the
Web interface. You can also configure Message Manipulation rules using the table ini file
parameter, MessageManipulations or CLI command, configure voip > sbc manipulations
message-manipulations.
