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 ). 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.
