8.1.1 Distinctive Ringing
Distinctive Ringing is applicable only to FXS interfaces. Using the distinctive ringing section
of the Call Progress Tones auxiliary file, you can create up to 16 distinctive ringing patterns.
Each ringing pattern configures the ringing tone frequency and up to four ringing cadences.
The same ringing frequency is used for all the ringing pattern cadences. The ringing
frequency can be configured in the range of 10 to 200 Hz with a 5 Hz resolution.
Each of the ringing pattern cadences is specified by the following parameters:

Burst Ring On Time:

Configures the cadence to be a burst cadence in the entire
ringing pattern. The burst relates to On time and the Off time of the same cadence. It
must appear between 'First/Second/Third/Fourth' string and the 'Ring On/Off Time'
This cadence rings once during the ringing pattern. Otherwise, the cadence is
interpreted as cyclic: it repeats for every ringing cycle.
Ring On Time:

specifies the duration of the ringing signal.
Ring Off Time:
The distinctive ringing section of the ini file format contains the following strings:
specifies the silence period of the cadence.

[NUMBER OF DISTINCTIVE RINGING PATTERNS]:
•
'Number of Distinctive Ringing Patterns' defining the number of Distinctive Ringing
signals that are defined in the file.
Contains the following key:

[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.
