How to use digital voice via third party router

[djenson2000]

Hi there, currently on BT Fibre 2 using a configuration that looks something like this 

However, in the MY BT page, i've recently had the notification that BT digital voice will be swapped too soon

My question is, how is Digital voice going to work in this situation. Double NAT (i.e. pluing TP link router into the smart hub 2 they provide) is not an option as it breaks mobile banking apps and streaming content outside the home.

Is there like and ATA adapter option for digital voice that can just be plugged into an ethernet port? 

Many thanks

As you are using a business hub 6 are you a BT business user. If so you need to post here

Nope, im not a business user. I got the BT Business hub to use as a modem for a BT residential line. This costs £30 vs spending £100 on a V167 modem.

If you want Digital Voice, you need to have the SH2 as the first device connected to line, end of.

You either need to connect the TP Link LAN to WAN and double nat or connect LAN to LAN and use the TP Link as a wap

Sucks really that bt have decided to do it like that, they have the fibre solution where you can plug into the ONT and still use your own router while having a landline - but oh well. Thank you for confirming my fears.

You can always move your voice service to a third party VoIP provider instead of DV

Not any more, that was FVA (fibre voice access) and is now discontinued.

There is another series of posts on here that explains how to use a third party router by keeping the BT SH2 as the first connection to the Fibre ONT. I have successfully done this with a Draytek 2962 however there is a slight catch but with a solution.

I set this up several months ago in anticipation of getting DV and it's been working fine however the Firewall in the SH2 has to be disabled and the WiFi disabled too otherwise there is the risk of connecting to the internet without a Firewall if the device you are using were to connect to either the 2.4 or 5GHz SSID in the SH2.

I've just been notified that my line is switching to DV so I ordered my "free" Handset and although my switchover date has not been set yet I thought I would see if the handset would connect to my SH2 and guess what it didn't . 

The catch is this, if the WiFi is disabled, that turns off everything including the DECT base station built into the SH2, the solution is to enable the WiFi but keep the 2.4 and 5GHz SSIDs turned off. This will leave the BT SH2 with the DECT working and the handset will register but also the BT WiFi HotSpot is enabled so be aware of this and make sure you do not connect anything to it as the Firewall will be disabled in the SH2.

There is absolutely no need to disable the firewall in the SH2 when connecting a third party router.

Turning off wifi doesn't disable DECT and Digital Voice.
