Purchased a Grandstream telephone adapter?

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.)

    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! 👍

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:
