User's Manual 36. SBC Manipulations
X-AC-Action: 'reply;response=<response code, e.g., 200>]'

To switch to a different IP Profile for the call (re-INVITE only), as defined in the
IP Group:
X-AC-Action: 'switch-profile;profile-name=<IP Profile Name>'
X-AC-Action: 'switch-profile;profile-name=<IP Profile
Name>;reason=<PoorInVoiceQuality or
PoorInVoiceQualityFailure>]'
If the IP Profile name contains one or more spaces (e.g., "ITSP NET"), enclose the
name in double quotation marks, for example:
X-AC-Action: 'switch-profile;profile-name="ITSP NET"'
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, 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.
