Version 6.2 207 February 2011
SIP User's Manual 3. Web-Based Management
Notes:
• For a detailed description on the syntax for configuring SIP message
manipulation rules in the Message Manipulation table, see ''SIP Message
Manipulation Description'' on page 506.
• SIP message manipulation is done on the inbound and outbound legs
(i.e., only after classification, inbound/outbound manipulations, and
routing).
• Each message can be manipulated twice, once for the source leg
manipulation rules and once in the destination leg (source and
destination IP Groups).
• SIP message manipulation rules configured on this page can be
assigned to an IP Group and determined whether they must be applied to
inbound or outbound messages (see ''Configuring IP Groups'' on page
119).
• 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.
• Manipulation of SDP body is currently not supported.
• The values entered in the table are not case-sensitive.
• For configuring Message Manipulation using the ini file, see the
parameter MessageManipulations.
¾ To configure SIP message manipulation rules:
1. Open the 'Message Manipulations' page (Configuration tab > VoIP menu > SBC
submenu > Manipulations SBC submenu > Message).
