The device can detect and report the following Special Information Tones (SIT) types from
the PSTN:
SIT-NC (No Circuit found)
SIT-IC (Operator Intercept)
SIT-VC (Vacant Circuit - non-registered number)
SIT-RO (Reorder - System Busy)
There are additional three SIT tones that are detected as one of the above SIT tones:
The NC* SIT tone is detected as NC
The RO* SIT tone is detected as RO
The IO* SIT tone is detected as VC
The device can map these SIT tones to a Q.850 cause and then map them to SIP 5xx/4xx
responses, using the parameters SITQ850Cause, SITQ850CauseForNC,
SITQ850CauseForIC, SITQ850CauseForVC, and SITQ850CauseForRO.

The X-Detect event notification process is as follows:
1.
For IP-to-Tel or Tel-to-IP calls, the device receives a SIP request message (using the
X-Detect header) that the remote party wishes to detect events on the media stream.
For incoming (IP-to-Tel) calls, the request must be indicated in the initial INVITE and
responded to either in the 183 response (for early dialogs) or in the 200 OK response
(for confirmed dialogs).
