Detecting a Far End Disconnect
Reference Manual (SIP Version)

To enable the far end tone detection:
1.
Set the
fxoFeocOnToneDetectionMode
variable.
2.
In the case of custom tone detection, set the frequency of the tone you want to detect in the
fxoEndOfCallToneCustomFrequency
variable.
You can set any value between 350 Hz and 620 Hz.
3.
Set the cadence to detect in the
fxoEndOfCallToneCustomCadence
variable.
A cadence is a series of frequencies that are played for a specified time, which makes up a tone.
The format for a cadence is:
on1,off1,on2,off2,on3,off3
In this string, “on” and “off” are numerical values that represent the time, in milliseconds, the
frequency can and cannot be detected, respectively. For instance, “2000,1000,2000,0” is a cadence
in which the frequency plays for 2 seconds, stops for 1 second, and plays for 2 more seconds. This
example is also equivalent to the string “2000,1000,2000”.
You can specify up to three “on,off” pairs. If you specify less than those six values, “0” values will
be added as necessary. Specifying more than six will only use the six first values.
A cadence that starts with a value of zero (0) is invalid and will not be applied. Note that the first
zero (0) found in the string signals the end of the cadence (i.e., “200,0,300” is the same as “200”).
•
To detect a continuous tone, use a single “on” value, e.g., “200, 0” (the off time is 0 ms.)
•
To detect a tone in which two or more frequencies are used, for instance with a
cadence of “200 ms, 500 ms, 300 ms, 400 ms”, in which the respective frequencies
would be “400 Hz, 300 Hz, 400 Hz, 500 Hz”, detect a frequency that comes twice or
more in the tone. In the above example, detect the 400 Hz frequency by using the
cadence “200 ms, 400 ms, 300 ms, 500 ms”. In this example, the 400 ms and 500 ms
off times represent the times that the 400 Hz frequency cannot be heard, even though
another frequency may be playing.
The “on” and “off” values can be from 0 to 32767.
4.
Set the repetition of the cadence to detect in the
fxoEndOf CallToneCustomRepetition
variable.
This is the number of times to detect the custom cadence to consider the custom end of call tone
has been detected.
5.
Restart the Mediatrix 1204 so that the changes may take effect.
Table 119:
Tone Detection Mode
Setting
Description
disable
Force end of call on tone detection is disabled.
countryTone
The Mediatrix 1204 tries to detect the tone specified for this purpose in the
current country’s tone specification. Some country specifications omit this
information. In that case, the unit behaves as if
fxoFeocOnToneDetectionMode
is “disable”.
customTone
Terminates a call on detection of a custom tone. In that case, proceed to Step 2.
Note:
A customized tone detection can only detect a single frequency. To detect tones made of multiple
frequencies, create the cadence for only one of the frequencies found in the tone.
