Purchased a Grandstream telephone adapter?
If you have purchased a Grandstream telephone adapter (ATA), it will come configured for the US telecom system as standard. As such, it will play back US style tones, sounds and some UK phone features may not work correctly unless you make some configuration changes via the devices web based GUI.

What are the UK regional settings for the Grandstream telephone adapters and how do I implement them?
Login to your Grandstream telephone adapters web based GUI by typing the IP address of the device into your web browser. (There is no need to enter "http://" before the IP address.)

    Purchased a Grandstream HT813 telephone adapter?
    The HT813 is an analog telephone adapter that features 1 analog telephone FXS port and 1 PSTN line FXO port in order to offer backup lifeline support using a PSTN line. Additional UK regional settings are required for this model and I have included them below.

    Navigate to the FXO PORT page:
    • Caller ID Scheme: SIN 227 - BT
    • FSK Caller ID Seizure Bits: 96
    • FSK Caller ID Mark Bits: 55
    • PSTN Disconnect Tone: f1=400@-30,f2=400@-30,c=0/0;
    • Country-based: UK
    • Impedance-based: COMPLEX3 -- 370 ohms + (620 ohms || 310nF)
    Grandstream HT813 UK Dial Plan:
    Code: Select all
    { L: 10[015] | L: 11[129] | L: 999 | L: 147[457-9] | L: 17070 | 155 | 11[68]xxx | 1[45]7[1-2] | 08001111 | 0845464x | 0[1235789]xxxxxxxxx | 1410[1235789]xxxxxxxxx | 14700[1235789]xxxxxxxxx | 00xxx. | x+ | \+x+ | *x+ | *xx*x+ }

The values you gave sound slightly different.
Hi @BrianG61UK and apologies for the late reply...

The British Telecom Suppliers' Information Notes (SIN 350 issue 1.8 dated September 2021) document titled "Openreach Public Switched Telephone Network (PSTN): Network Tones And Announcements" tells us that the dial tone composition is 350 Hz plus 440 Hz.

So based on that information, the syntax I used in my original post above is correct.

Thanks for this guide.

I just bought a HT802 and although haven't got the correct RJ11 converter for my phone, I've set it up and it's showing registered and ready to go on Sipgate.

Can I assume that the settings for HT812 can be all used for the HT802 or are there some differences?

Correct! 👍
#6571
Thank you. My Rj11 lead arrived today and all works well. So pleased at how smoothly this transition has been and of course leaving BT and the noisy line they've been unable to fix for nearly 8 years. This will save me a ton and allow me to hear people again. :-)

Would just like to express my thanks to the OP for this guide too. Have finally waved goodriddancebye to Virgin and ported our long held and well travelled landline number across to my existing sipgate account but had run into a few call handling oddities using sipgates config guide for the Grandstream HT801 that we're using to retain use of our olde BT8610 DECT handsets (and more specifically their trueCall functionality).

All seems to be working perfectly now. :ok_hand:

Hi, thanks for this

All of these settings worked for me other than Hook Flash Timing, when I change that I can't make calls anymore. The standard setting or disabling hook flash both fix it.

Any idea why that is? I am using a pulse-dialing phone if that helps

A Hook Flash is nothing more than hanging up and picking up the line very quickly. By default, Grandstream telephone adapters are set to do a Hook Flash in 300 milliseconds. In some instances, this is too slow for the phone system to detect, so you’ll hear a click but the line will not go on hold and you will not get the second dial tone. Changing the duration of the Hook Flash is usually the fix for this problem.

The correct UK PSTN settings are 60 milliseconds minimum and 200 milliseconds maximum. However, if you're using a PBX configured to use other values then set them accordingly! You can of course leave these at their defaults if you do not want to place a call on hold or obtain a second dial tone (make a second call after placing the first on hold).

Add the following to your dial plan:
Code: Select all
<=01983>[2-9]xxxxx

As an update on this, I think I have worked out the problem. The hook flash seems to work fine when set to 70, or even 61 at a minimum.

I believe that because I'm using a rotary phone with pulse dialing as I mentioned the minimum needs to be above 60ms. I don't know exactly how they work, but on an old rotary phone you used to be able to dial a "1" with a hook flash of 60ms, and if you got good at it I've heard you could dial a full number this way. (2 60ms hook flashes for a "2", etc.)

I set the hook flash to the 60-200 UK standard, and I can in fact dial a "1" with a quick hook flash but this breaks the ability to actually dial a number in the regular way. Why that is I'm not exactly sure, but I assume it's some sort of bug with the ATA where it's getting confused by what the signal it's receiving is. I would guess it is unsure if each pulse it gets is dialing or hook flashing, so what it does is it dials a "1" and then hangs up, which is what happens if I check the outgoing calls log.

I have left hook flashing on 70-200 just to give a bit of leeway, and it seems to work a lot better than the American standard, which just felt far too slow for me.

Just thought I'd update this thread now I've had more of a play around with it in case this information is helpful to anyone else in the future.
