14.4.1 SIT Event Detection
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.
