■ 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).
