In SIP, the Distinctive Ringing pattern is selected according to the Alert-Info header in
the INVITE message. For example:
Alert-Info:<Bellcore-dr2>
--or--
Alert-Info:<http://…/Bellcore-dr2>
"dr2" defines ringing pattern #2.
If the Alert-Info header is not present, the default ringing tone #0 is played.
An example of a ringing burst definition is shown below:
#Three ringing bursts followed by repeated ringing of 1 sec on and 3 sec off.
