Grandstream GXW4104 - UK - 3rd party hang up not detected

[JamesC]

Hi everyone.

The subject says it all really.

I'm trying to setup a Grandstream GXW4104 in the UK. It's connected to a single BT socket and refuses to detect the other party hanging up.

On hang-up I hear a clear tone (which I have recorded/analysed and found to be 400Hz). I have set what I believe to be appropriate settings for this tone but it still does not work. (Note that the 400Hz figure also matches all the specs I found on the Internet for a UK disconnect tone).

Here are my settings:

FXO Lines page
Enable Current Disconnect: No
Enable Tone Disconnect: Yes
Enable Polarity Reversal: No
AC Termination Impedance: 370 Ohm + (640 Ohm || 310nF) <- Correct UK setting

Channels page
Dial tone: ch1-4:f1=350@-11,f2=440@-11,c=0/0;
Ringback tone: ch1-4:f1=440@-11,f2=480@-11,c=200/400;
Busy tone: ch1-4:f1=400@-11,f2=400@-11,c=300/0;
Reorder tone: ch1-4:f1=400@-11,f2=400@-11,c=300/0;
Confirmation tone: ch1-4:f1=350@-11,f2=440@-11,c=10/10;

Please note that I have set the Busy and Reorder tones to the same setting, in accordance with various pieces of information I have found on the Internet.

I have also tried several other settings for Busy/Reorder tone, including:
ch1-4:f1=400@-11,f2=400@-11,c=400/0;
ch1-4:f1=400@-11,f2=0@-11,c=400/0;
ch1-4:f1=400@-5,f2=400@-5,c=300/0;

Can anyone assist me?

I'm sure there must be someone in the UK who has this device working!

Cheers,

Jame

Hi James

I spent a couple of hours last night messing about with the 4104.

I am afraid I have to go into a meeting now but in the meantime have alook at the firmware version which can be foun under the status tab and if it is not 1.0.1.2 or higher I would update it from:

http://www.grandstream.com/DOWNLOAD/FIRMWARE/GXW4104_GXW4108/Release_GXW4104_GXW4108_1.0.1.2.zip

You have to have a tftp server on your machine but if you look at the manual you can read about this on page 29:

Hope this helps. If not I will try to help later.

Thanks Simon. I had already upgraded the firmware though.

My versions are as follows:

Program-- 1.0.1.2
Loader-- 1.0.0.7
Boot-- 1.0.1.1

Hi James,

Just grabbed 5 minutes. The obvious difference from our box (which is now working at last!) is that we have enable current disconnect set to yes and tone disconnect to no.

Worth a try.

If not I should get 10 mins again in a couple of hours.

[JamesC]

Yeah, I also tried current disconnect. I'm sure it should be tone disconnect though. (As I definitely hear a tone!)

I'm currently waiting for a call back from my phone company (we don't use BT directly, we use Worldwide) where they should confirm which disconnection method is used.

 

[JamesC]

Oh.. and do you actually have disconnection detection working properly?

Cheers,

James

Our box on a BT line does work fine..... but we had a problem with the first box that was useless and never worked at all. Ex=ventually got it exchanged.

Simon

 

[JamesC]

Hmmm.. that doesn't bode well. :-(

I solved this problem with a BT line by using the dial tone as the disconnect tone:

f1=350@-11,f2=440@-11,c=0/0;

Our office phone lines at least disconnect at the exchange and revert to a dialtone, and the grandstream box will detect that and hang up.

Correction; this does not solve the problem, as the ATA rings, hangs up, rings, continuously...
