22.4 Configuring Pre-Parsing Manipulation Rules
The Pre-Parsing Manipulation Set table lets you configure up to 10 Pre-Parsing
Manipulation Sets. Pre-Parsing Manipulation allows you to manipulate incoming SIP
messages (dialog-initiating and in-dialog) before they are parsed (as an object) by the
device. In other words, messages can be manipulated in their original format (plain text) as
received from the network. Pre-Parsing Manipulation may be useful, for example, to
overcome parser strictness or to “allow” possible parsing errors.
To use a configured Pre-Parsing Manipulation Set, you need to assign it to a SIP Interface
(see Configuring SIP Interfaces on page 325). The device performs Pre-Parsing
Manipulation before Pre-Classification Manipulation and Classification.
Pre-Parsing Manipulation rules are defined by the SIP message element to manipulate (for
example, INVITE), the pattern based on regular expression (regex) to search for (match) in
the incoming message, and the regex pattern to replace the matched pattern.
Note: For a detailed description of supported regex syntax, refer to the Message
Manipulation Reference Guide .
Pre-Parsing Manipulation is configured using two tables with parent-child type relationship:

Parent table: Pre-Parsing Manipulation Sets table, which defines a descriptive name
for the Pre-Parsing Manipulation Set.

Child table: Pre-Parsing Manipulation Rules table, which defines the actual
manipulation rule. You can configure up to 10 rules per Pre-Parsing Manipulation Set.
The following procedure describes how to configure Pre-Parsing Manipulation Sets through
the Web interface. You can also configure it through other management platforms:

Pre-Parsing Manipulation Sets table: ini file (PreParsingManipulationSets) or CLI
(configure voip > message pre-parsing-manip-sets)

Pre-Parsing Manipulation Rules table: ini file (PreParsingManipulationRules) or CLI
(configure voip > message pre-parsing-manip-rules)

To configure Pre-Parsing Manipulation Sets:
1. Open the Pre-Parsing Manipulation Sets table ( Setup menu > Signaling & Media tab
> Message Manipulation folder > Pre-Parsing Manipulation Sets ).
