X-AC-Action: 'disconnect'
X-AC-Action: 'disconnect;delay=<time in ms>'
■ To resume a previously suspended call:
X-AC-Action: 'abort-disconnect'
■ To automatically reply to a message without forwarding the response to the other side:
X-AC-Action: 'reply'
■ To automatically reply to a message with a specific SIP response without forwarding
the response to the other side:
X-AC-Action: 'reply;response=<response code, e.g., 200>'
■ To override the device's handling of SIP REFER messages, which is configured by the
'Remote REFER Mode' [IpProfile_SBCRemoteReferBehavior] parameter.
The X-AC-
Action header can be added to the incoming SIP REFER request using Message Manipulation
rules. This is useful if you don’t want the settings of this parameter to apply to all calls that are
associated with the IP Profile. For example, if you configure the 'Remote REFER Mode'
parameter to
Handle Locally , all incoming SIP REFER requests associated with the IP
Profile are terminated at the device. However, you can configure a Message Manipulation rule
with the proprietary header to override this parameter setting and allow the device to forward
the REFER requests as is for calls with a specific URI, for example. You can configure
Message Manipulation rules to add this X-AC-Action header for REFER handling, with one of
the following values:
● To allow the device to forward the REFER as is, regardless of the 'Remote REFER Mode'
parameter settings:
X-AC-Action: 'use-config;refer-behavior=regular'
● To allow the device to handle (terminate) the REFER request regardless of the 'Remote
REFER Mode' parameter settings:
X-AC-Action: 'use-config;refer-behavior= handle-locally'
■ 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"'
