Disconnection Tone

[marck]

CIMG1103.zipDear Sir,

 

I have a problem with the disconnection tone.

My Trunks lines are connected directly to the 4 analog channel Dialogic card.

And when i disconnect the dialogic doesn't release the line, i tried to mesasure the frequency and on/off parameteres using the PBx expert but with no luck with the results.

I recorded the disconnection tone for you, and i appreciate if you can send me back the parameters.

 

Thank you for your support.

Have you read the instructions in the VoiceGuide Help file's section on "End of Call Detection"?

 

It has Step-by-step instructions on how to set the disconnect tone parameters.

 

Online copy of that Help file section is available here: http://www.voiceguide.com/vghelp/html/Disc...ctionDetect.htm

I did read the instructions.

And after measuring the signal i got the following parameters:

 

Freq1: 425

Freq1 dev: 40

Freq2: 0

Freq2 dev: 0

On time: 20

On time dev: 5

Off time: 20

Off time dev: 5

Repetition count: 2

 

But still the Dialogic card doesn't release the line after i disconnect.

Can you please measure it and get back to me with the results maybe i missed something.

The recording shows this is an unusual type of tone. The end of tone is not well defined, and it is composed of many frequencies, rather the one or two dominant frequencies.

 

The length of the ON section of the tone is about 200ms, but then the tone dies off over the next 100ms, so you could say length of tone is actually 300ms...

 

Overall cycle is about 480ms.

 

The frequencies are a real problem though. It's hard to say if just specifying 425Hz will be sufficient as it does not stand out that much from other frequencies (which are mostly it's harmonics).

 

Try these settings:

 

Freq1: 425

Freq1 dev: 40

Freq2: 0

Freq2 dev: 0

On time: 25

On time dev: 10

Off time: 25

Off time dev: 10

Repetition count: 1

 

but if they do not work then you should look at using other phone lines which have better defined disconnect tone or offer loop current drop signaling.

 

Which Dialogic card are you using?

Thank you for your help.

It's working...
