Hi,

I upload the recording disconnect tone , I hope if anybody can analyze it and give what best values should I use .

Thanks

any idea with thanks ??

I analyzed it and it's a signal with a frequency around 425 Hz and the cadence is ~ 250 ms ON and 250 ms OFF.

so the config should be similar to this:

dualtone disconnect
frequency 425
cadence 250 250

Hi Mohamed ,

many thanks for your reply.

I test it at this configuration with fail result , the main problem when the call come from outside to AA at CUC , and when other party hang up the phone complete message and go to VM and waiting until VM message maximum time finish.

this information I get it from PSTN company.

Thank you for contacting us. According to your request kindly find  The Jordanian PSTN network specifications for stand-alone-services as follow:

 

-Dial tone -    ( 420 +/- 5 Hz x40, continuous )

-Busy tone -    (420 +/- 5 Hz x40  , 500 ms on 500 ms off )

-Congestion tone -    ( 420 +/- 5 Hz x40  , 167 ms on 167 ms off)

-Holding tone -   420x40   0.5 on 8.0 off (1400 +/- 50 Hz x40 , 400 ms on 1500 ms off) 

-Howler tone -   950   continuous ( 3000 +/- 5 Hz, continuous )

-Intrusion tone -    (1400 +/- 50 Hz x40 ,  2 s on 15 s off  400 ms on)

-Number unobtainable tone -   ( 420 +/- 5 Hz x40 ,  announcement )

-Ringing tone -    ( 420 +/- 5 Hz x40 , 1200 ms on 4800 ms off )

-Special information tone ( f1=950 +/- 50 Hz, f2 = 1400 +/- 50 Hz, f3 = 1800 +/- 50 Hz.) x40 ,  (1000 ms on 1000 ms off)

-Call waiting tone -    (1400 +/- 50Hz x40, 175 ms on 175 ms off 175 ms on 3500 ms +/-1500ms off)

 

signal modulated by 40

 

 

That's strange!

Can you post your show-run to double check that the dualtone disconnect configuration is correctly applied to voice ports ?

Also, try the busy tone variant that your telco gave you (change the cadence from 250-250 to 500-500 )
