Does anybody have any idea abt the Disconnect tone for telecom companies in Hong kong?

As per documents available on web and also analysis of the disconnect-tone by the process described here the string comes out to be

480@-20,620@-20;4(.5/.5/1+2)

However, its not detected by SPA 3000 as the disconnect tone.

I am sure abt the frequencies and the on & off time but not so sure abt the power parameter and also the cycle time.

Any idea as to how these can be calculated from the disconnect tone?

I'm using:

480@-30,620@-30;4(.5/.5/1+2)

Definitely the cycle time is .5/.5 (I also saw it written somewhere on OFTA's website).

Thanks for ur reply

I am on PCCW and i have tried the exact same settings mentioned by you, but the disconeect tone is still not detected.

Any other settings that u maybe using regarding the following
PSTN Disconnect Detection
Detect CPC: Detect Polarity Reversal:
Detect PSTN Long Silence: Detect VoIP Long Silence:
PSTN Long Silence Duration: VoIP Long Silence Duration:
PSTN Silence Threshold: Min CPC Duration:

I'm on a PCCW line as well. Before I changed the timing to 0.5/0.5, with the default 0.25/0.25 it did not work. Here are the settings:

PSTN Disconnect Detection
Detect CPC: Yes Detect Polarity Reversal: Yes
Detect PSTN Long Silence: No Detect VoIP Long Silence: No
PSTN Long Silence Duration: 30 VoIP Long Silence Duration: 30
PSTN Silence Threshold: medium Min CPC Duration: 0.2

Detect Disconnect tone: Yes
Disconnect Tone: 480@-30,620@-30;4(.5/.5/1+2)

Perhaps we run different firmware versions? I had tried to upgrade to the 3.1.7g but I had horrible echo problem, so I quickly downgraded back to good old 2.0.13g, which is what I have now running quite well... Then I noticed that the 3.1.7g was withdrawn from http://www.sipura.com/support/ for a while, and now they offer a 3.1.10d (with the release notes of the previous 3.1.7g :roll Perhaps I should give it a try, if only I knew what the supposed improvements are...
