frequencies are supported) and the tone cadence. This is specified by 2 sets of ON/OFF periods,
but Users can discard the use of the first On/Off cycle by setting the relevant parameters to zero.
When the tone is made up of a single frequency, the second frequency field should be set to
zero.
For a continuous tone (such as dial tone), only the "First Signal On time" should be specified. In
this case, the parameter specifies the detection period. For example, if it equals 300, then the
tone is detected after 3 seconds (300 x 10 msec).
Note 1: When defining several continuous tones, the "First Signal On Time" parameter should have
the same value for all tones.
Note 2: The tones frequency should differ by at least 40 Hz from one tone to other defined tones.

Default Template for Call Progress Tones

The Mediant 2000/SIP is initialized with the default Call Progress Tones configuration template
shown in Table 5-5. To change one of the tones, edit the default call progress.txt file.
For example, to change the dial tone to 440 Hz only, replace the #Dial tone section in Table 5-5
with the following text:
#Dial tone
[CALL PROGRESS TONE #1]
Tone Type=1
Low Freq [Hz]=440
High Freq [Hz]=0
Low Freq Level [-dBm]=10 (-10dBm)
High Freq Level [-dBm]=32 (use 32 if only single tone is required)
First Signal On Time [10msec]=300; The dial tone is detected after 3 sec
First Signal Off Time [10msec]=0
Second Signal On Time [10msec]=0
Second Signal Off Time [10msec]=0
Users can specify several tones of the same type using Tone Type definition. These additional
tones are used only for tone detection. Generation of specific tone is according to the first
definition of the specific tone. For example, the User can define an additional dial tone by
appending the second dial tone definition lines to the tone ini file. The Mediant 2000/SIP reports
dial tone detection if either of the two tones is detected.
