[Ringing Pattern #X]: Contains the Xth ringing pattern definition (starting from 0 and
not exceeding the number of Distinctive Ringing patterns defined in the first section
minus 1) using the following keys:
• Ring Type: Must be equal to the Ringing Pattern number.
• Freq [Hz]: Frequency in hertz of the ringing tone.
• First (Burst) Ring On Time [10 msec]: 'Ring On' period (in 10 msec units) for
the first cadence on-off cycle.
• First (Burst) Ring Off Time [10 msec]: 'Ring Off' period (in 10 msec units) for
the first cadence on-off cycle.
• Second (Burst) Ring On Time [10 msec]: 'Ring On' period (in 10 msec units)
for the second cadence on-off cycle.
• Second (Burst) Ring Off Time [10 msec]: 'Ring Off' period (in 10 msec units)
for the second cadence on-off cycle.
• Third (Burst) Ring On Time [10 msec]: 'Ring On' period (in 10 msec units) for
the third cadence on-off cycle.
• Third (Burst) Ring Off Time [10 msec]: 'Ring Off' period (in 10 msec units) for
the third cadence on-off cycle.
• 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.
