Fourth (Burst) Ring On Time [10 msec]: 'Ring Off' period (in 10 msec units) for
the fourth cadence on-off cycle.
•
Fourth (Burst) Ring Off Time [10 msec]: 'Ring Off' period (in 10 msec units) for
the fourth cadence on-off cycle.
Note: 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 missing, 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.
