SPA 400 Call Disconnect Tones

Answered Question
Oct 15th, 2009

After much searching I have located the call disconnect tones for South Africa but listed in Sipura-speak as 400@-30,400;@-30;4(.5/.5/1+2)

the Tone tab on the SPA400 web inteface lists the config options in a different format.

Tone on fraction = ? %
High cutoff frecuency = ? Hz
Low cutoff frecuency = ? Hz
First Tone Detection Time
On = ? ms
Off = ? ms
Repeat Count = ?

2nd Tone Detection Time
On = ? ms
Off = ? ms
Repeat Count = ?

I would be immensely grateful if someone could help me translate.

I have this problem too.

Here is what the parameters mean in your formula:

425@-30,425@-30;2(.3/.4/1+2) where 425=tone frequency, -30dB=level, 2=number of cycles of tone 1 (third parameter in parenthesys) 0.3s ON and 0.4s OFF

Tone on = 40%

High Cutoff = 450

Low Cutoff = 400

First Tone

On = 300

Off = 400

Repeat = 2

PLEASE post your results.

According to the formula produced and the research I have done, try these parameters:

44%

460

340

On=500

Off=500

repeat count 4

can you please explain where the tone on fraction value of 40% came from?

how did you come up with high =450 and low=400 while both frequency 1 and 2 are equal to 425?

appreciate your help

Hello,

you know that the tone is formed by mixing of 2 tones with different (or equal) frequencies.

So, in your example:

425@-30,425@-30;2(.3/.4/1+2)

- 425Hz is the tone frequency of the first tone,

- 425Hz is the tone frequency of the second tone.

On the other hand, low cutoff frequency and high cutoff frequency define a band where 2 frequency should be in.

Since in your example 2 frequencies are 425 Hz, it is enough to specify range between 400 Hz and 450 Hz.

About "Tone on = 40%".

(third parameter in parenthesys) 0.3s ON and 0.4s OFF,

which means that the mixture of 2 tones will play for 0.3 seconds and will be silent for 0.4 seconds.

The whole cycle is 0.3 + 0.4 = 0.7 seconds.

I suppose that "Tone on" shows what part of the whole cycle the tone is played:

0.3 / 0.7 = 42.86%

Of course, if I didn't understand something properly, feel free to correct me :)

Low Cutoff frequency: 425

First tone:

On 200

Off 200

Second Tone:

On 200

Off 200

Third Tone:

Hello,

could you please provide me the proper parameters to be inserted in the 'tone' section of the spa400 for Italy?

Thank you in advance.

Hello everyone,

After reviewing this post and contacting Cisco Support with a similar problem, I wanted to ask if someone out there has the disconnect tones for the Venezuelan area.

Best regards,

Kaleco

kaleco.dugarte Sun, 11/01/2009 - 08:35

Juan,

Thank you for your prompt reply.  From what I've read on 3AM SYSTEM's website, some countries use the Congestion Tone as the Disconnect tone; and, since your table doesn't show a Disconnect Tone for Venezuela, I will try to configure the parameters specified for the Congestion Tone.

Given this case, can someone please confirm which parameters should I configure based on this Sipura format: 425@-10; 10(0.25/0.25/1) ?  I know that some of it should look like this:

Tone on = ???

High Cutoff = Above 425??

Low Cutoff = Below 425???

First Tone

On = 250

Off = 250

Repeat = 1

BR,

Kaleco

Gents,

For those interested, I want to update this discussion on what I tried while configurind the Disconnect Tone for Venezuela.  Based on Juan's table and the information found on www.3amsystems.com website, I used the Busy Tone as the Disconnect tone:  425@-10;10(0.5/0.5/1).

After a little bit of trial and error, this is what I used on the SPA400 / Tone configuration tab:

Tone on fraction:     40%

High cutoff frequency:     450Hz

Low cutoff frequency:     400Hz

First Tone On 500(ms)

First Tone     Off     500(ms)

Repeat count : 10

It's been working fine for the last couple of days without a single FXO port stuck in the Off-Hook position.

Regards,

Kaleco

Kaleco,

I am glad to hear the information I found was helpful to you, I just saw your replies and that website 3AM was indeed where I found the information. I also noticed that they did not specify the disconect tone so you assumed well in trying the congestion tone. 

Regards

Juan M. Unda

Oh, and another question (please bare with me), how do I translate the -10db on 425@-10 into the SPA400 configuration?

kradoyno Tue, 11/10/2009 - 05:53

Hi, everyone,

can somebody tell me the Call Disconnect Tones for Russian Federation.

Any help will be much appreciated.

Thank you very much, Bill :)

Actually, the client is from Armenia.

He tried the settings that you proposed to me:

350 @ -30,350 @ -30;4(.25/.25/1+2)

I advised him to enter the following in Tone Tab of SPA400:

Tone on fraction: 49%

High cutoff frequency: 400 Hz

Low cutoff frequency: 300 Hz

First tone On: 250ms

First tone Off: 250ms

Repeat count: 4

The problem is that after the call is finished, the PSTN line is not freed.

The only solution is to assign "Tear down FXO port when silence detected for: 20 s"

But this sometimes leads to interruption during an active call.

That's why I am asking you for Call disconnect tone settings for Armenia.

Evidently they are different from Russian Federation's Call disconnect tone settings.

Thank you very much for your help.

Best regards,

Kino Radoynovski

Can somebody present to me info for Call Disconnect Tone for Armenia?
