4.13 Step 13: Configuring SIP Message Manipulation
Rules
This step shows how to configure SIP message manipulation rules (configured in the
Message Manipulations table).
SIP message manipulation rules can include insertion, removal and/or modification of SIP
headers. Multiple manipulation rules can be configured for the same SIP message. After
configuring the SIP message manipulation rules, assign them to the relevant IP Group (in
the IP Group table) and determine whether they must be applied to inbound or outbound
messages.
See an example below of a message manipulation rule configuration; use the E-SBC
User's Manual for detailed instructions on how to configure message manipulation rules
according to your requirements.
In the example scenario, the configured manipulation rule manipulates the P-Asserted-
Identity user part of the header, and replaces it with the user part that appears on the
Referred-By header.
To configure SIP message manipulation rules:
1. Open the Message Manipulations page (Configuration tab > VoIP > SIP Definitions
> Msg Policy & Manipulation > Message Manipulations).
Figure 4-37: Message Manipulations Page
