• 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 Alert-Info header
that is included 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.
