Below are header manipulation examples:

Example 1

Rule:

Test the Request-URI transport type. If 1 (TCP), then modify the URL portion of the From header:

■ Message Type: Invite.request
■ Condition: header.REQUEST-URI.url.user == '101'
■ Action Subject: header.Remote-Party-Id.url
■ Action Type: Modify
■ Action Value: 'sip:3200@1.1.1.1;tusunami=0'

Result:

 
Remote-Party-ID: <sip:3200@1.1.1.1;tusunami=0>;party=calling;npi=0;ton=0

Example 2

Rule:

If the method type is 5 (INVITE), then modify the Remote-Party-Id header:

■ Message Type: Invite.request
■ Condition: header.REQUEST-URI.url.methodtype == '5'
■ Action Subject: header.Remote-Party-Id.url
■ Action Type: Modify
■ Action Value: 'sip:3200@110.18.5.41;tusunami=0'

Result:

 
Remote-Party-ID: <sip:3200@110.18.5.41;tusunami=0>;party=calling;npi=0;ton=0

Example 3

Rule:

For all request URI's whose method types are 488, modify the message type to a 486:

■ Message Type: Any
■ Condition: header.request-uri.methodtype=='488'
■ Action Subject: header.request-uri.methodtype
■ Action Type: Modify
■ Action Value: '486'

Result:
