They can also be used to make changes in the Session Description Protocol (SDP), which is used to negotiate media. Common SIP Message Normalization Scenarios This section provides several SIP message normalization scenarios that have been seen frequently. Each scenario includes the configuration required on Cisco IOS for your reference and a screenshot from the SIP Profile Test Tool that is mentioned in the Introduction.
