requesting a specific event detection:
X-Detect: Request=[event type to detect]

X-Detect header in the SIP response message -- SIP 183 (for early dialogs) or 200 OK
(for confirmed dialogs) -- sent by the device to the application server specifying which
of the requested events it can detect (absence of the X-Detect header indicates that
the device cannot detect any of the events):
X-Detect: Response=[supported event types]

Each time the device detects the supported event, it sends an INFO message to the
remote party with the following message body:
Content-Type: Application/X-Detect
Type = [event type]
Subtype = [subtype of each event type]
The table below lists the event types and subtypes that can be detected by the device. The
text shown in the table are the strings used in the X-Detect header. The table also provides
a summary of the required configuration. For SBC calls, event detection is enabled using
the IPProfile_SBCHandleXDetect parameter in the IP Profiles table (see Configuring IP
Profiles on page 423).
