CHAPTER 26 SBC Manipulations
Mediant 4000 SBC | User's Manual
For example, to use the X-AC-Action header to switch IP Profiles from "ITSP-Profile-1" to "ITSP-
Profile-2" during a call for an IP Group (e.g., IP PBX) if the negotiated media port changes to 7550,
perform the following configuration:
1. In the IP Profiles table, configure two IP Profiles ("ITSP-Profile-1" and "ITSP-Profile-2").
2. In the IP Groups table, assign the main IP Profile ("ITSP-Profile-1") to the IP Group using the
'IP Profile' parameter.
3. In the Message Manipulations table (see Configuring SIP Message Manipulation ), configure
the following manipulation rule:
● Manipulation Set ID: 1
● Message Type: reinvite.request
● Condition: body.sdp regex (.*)(m=audio 7550 RTP/AVP)(.*)
● Action Subject: header.X-AC-Action
● Action Type: Add
● Action Value: 'switch-profile;profile-name=ITSP-Profile-2'
4. In the IP Groups table, assign the Message Manipulation rule to the IP Group, using the
'Inbound Message Manipulation Set' parameter.
In the above example, if the device receives from the IP Group a re-INVITE message whose media
port value is 7550, the device adds the SIP header "X- AC- Action: switch- profile;profile-
name=ITSP- Profile- 2" to the incoming re- INVITE message. As a result of receiving this
manipulated message, the device starts using IP Profile "ITSP-Profile-2" instead of "ITSP-Profile-
1", for the IP Group.
