The figure below illustrates a SIP message manipulation example:
Figure 20-2: SIP Header Manipulation Example
Notes:
• For a detailed description of the syntax for configuring SIP message
manipulation rules, refer to SIP Message Manipulations Quick Reference
Guide.
• For the IP-to-IP application, the outgoing message is re-created and
thus, SIP headers that are not relevant to the outgoing SIP session (e.g.,
Referred-By) are not included in the outgoing message. Therefore, if
required, manipulations on such headers should be handled in inbound
manipulation.
• The values entered in the table are not case-sensitive.
• For the SBC application, SIP 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.
