SIT TONE detection in asterisk 10.4.0 version


do we have separate reason code and hangupcause in asterisk 10.4.0 version for the SIT TONE detection. because when I tried to make outbound calls from asterisk, I have been receiving the same response code and hangup cause (3_0) for both ringing no answered call and SIT TONE detected call.

Anyone faced the same problem? please let me know how to recognize/identify the SIT Tone in asterisk 10.4.0.


There is actually more than one SIT tone, although I don’t know if Asterisk can tell them apart.

Ok david, if SIT Tone is more than one , what reason/hangup code asterisk is using to them?

Any idea?
