Almost every Telephone Company around the world uses a different Disconnect Tone.
To "translate" your Telco's one, you can do the following:

Overview:

The idea is to record the disconnect tone on a wav file on your computer and then analyze it using Sigview.

What you need:

- Xlite (softphone you can download at: www.xten.com)
- Sound Recorder (the one included with every Windows OS)
- SigView (Signal analyzer you can download at: www.sigview.com)
- 2 FWD numbers (sign for 2 accounts on www.freeworlddialup.com)

Procedure:

SETTING THINGS UP

1- Configure the first FWD# (eg.123400) on your Sipura's "PSTN Line" tab.

2- Configure the second FWD# (eg.123401) on your Xlite softphone.

3- Open the Sound Recorder of your choice

4- Double-click the speaker icon on the system tray and go to "Options"->"Properties" menu.
On the properties window, mark the "Recording" radio button and make sure "Wave Out Mix" is checked in the "Show the following volume controls" box.
Press OK and you'll see the "Recording Control".
By default, the "Microphone" is selected, so change it to "Wave Out Mix". (this will make the recorder to get every sound that goes through the speakers).

RECORDING THE FAMOUS "DISCONNECT TONE"

1- Make a call to the PSTN line that goes to your Sipura. (from your cell phone for example)

2- After authenticating on the sipura, dial the second FWD# (eg.123401) so Xlite will start "ringing".

3- Answer the call, and make sure it establishes correctly.

4- Now hang up your cell phone, so the PSTN line on the sipura will get the "disconnect tone". (You will start listening the disconnect tone on your computer)

5- Start recording immediately! (save the .wav file somewhere on your hard disk)

"TRANSLATING" THE TONE

1- Open Sigview and go to "File"->"Open Signal" menu. Choose the file you just saved in the Sound Recorder.

2- Go to "Signal Tools"->"FFT Spectrum Analisys".

3- Look for the highest peak (of this red graph) and place the mouse pointer on it.

4- On the status bar, look for the "X:" value (eg.416.532) This is the freq. you need!



5- Close the TTF graph and get back to the blue one to get the times for the tone and the silence.

6- Place the mouse at the begining of the tone (bold part) and right-click to choose "set mark here". (see the picture)

7- Place the mouse at the end of the tone and place a mark here too.



8- Do your math, and rest the second value minus the first one to get the amount of seconds.
(eg. 1.111 - 0.906 = 0.205)

9- Repeat steps 7-8 but with the silence part (eg. 1.298 - 1.111 = 0.187).



10- Substitute the values you collected in the following string: (round the time values)

X@-30,X@-30;Y(A/B/1+2)

where:
X = The frequency in Hz. (mine 416)
Y = The cycles the pattern repeats (I used 4)
A = Time in seconds for the frequency (mine .200)
B = Time in seconds for the silence (mine .200)

So, in the example, I would enter this on the disconnect tone value of the sipura:

416@-30,411@-30;4(.2/.2/1+2)

Important:
The sipura gives a 10% of error for the frequencies, so it doesn't to be the "exact" value.

It worked for me, so I hope it helps you find your Telco's Disconnect Tone.
