User's Manual
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 SIP Group Name (IPGroup_SIPGroupName) parameter overrides inbound
message manipulation rules that manipulate the host name in Request-URI, To,
and/or From SIP headers. If you configure a SIP Group Name for the IP Group
(see Configuring IP Groups on page 283) and you want to manipulate the host
name in any of these SIP headers, you must apply your manipulation rule
(Manipulation Set ID) to the IP Group as an Outbound Message Manipulation Set
(IPGroup_OutboundManSet), when the IP Group is the destination of the call. If
you apply the Manipulation Set as an Inbound Message Manipulation Set
(IPGroup_InboundManSet), when the IP Group is the source of the call, the
manipulation rule will be overridden by the SIP Group Name.
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.

To configure SIP message manipulation rules:
1. Open the Message Manipulations page (Configuration tab > VoIP menu > SIP
Definitions > Msg Policy & Manipulation > Message Manipulations).
2. Click Add; the following dialog box appears:
