Hi,

Is the above telephone compatible with EE digital voice?
The BT/EE website suggests that existing phones can be used by plugging into the phone port on the rear of the smart hub sh31b. I am finding on a weekly basis the phone loses dial tone, if you call in the phone will ring but on answer observe one way transmission, I cannot hear incoming caller but they can hear me. Hub has been changed. A power reset returns dial tone and normal operation.

@Terry964 The loss of dial tone is probably nothing to do with your existing phone but the EE DV service getting mixed up. The phone is plugged into the rear off the router or to a remote adapter, but this is only if you have the DV system. You do not say in your post, where you have your landline plugged into just now its a little vague. Any DECT style phone can be plugged in, the features that you get depend on both the DV and the Handset that you purchase. I would report that you are having issues with your phone, it may get better with time as the router is being updated all the time but its not 100% of the way yet. HTH Link below to the BT about that model.

Hi JimM11
I have a male to male tele lead plugged from the phone port rear of the the hub where the DV line comes in, the other end of tele lead plugs into the existing house extension wiring in order for the dect phone to be used from the downstairs lju by the front door. I have raised a fault into bt/ee to run a wireshark trace as fault is still on hoping they can figure out what’s causing the loss of speech path.

@Terry964 Are you coming into the router with FTTP and ONT modem service or still using the copper on an older fttc? your post does not make it clear, there is a special type of Master Socket if using the older copper cabling, but not many know/use that at present. Let the forum know when you get time. Edit: but as long as the original BT cable out is disconnected, and wiring changed to suit it should in theory be ok. Copy of link i found on BT forum site. Pretty sure the new socket was just to ensure nothing was sent back up the cable line... 

Solved: Keeping phone extensions working with Fibre Broadb... - BT Community

I am connected from fibre to the cab then 2 wire copper to openreach 2 part master socket. I do not need to use an asdl filter as I have segregated the internal house wiring away from the master socket so there is no need to use an ADSL filter. My landline is now voip and not traditional 2 wire 50V. Hope that makes sense. Trying to get this problem to higher tier support is proving difficult as 1st line support state there is no fault and reluctant to pass onto TMC, hence need a wire shark trace to prove where the fault is. As you say this setup in theory should work but somethings not right.

@Terry964 Got you, i would when you have the next problem take the phone and plug it right into the back of the router. Same issue then down to incoming signal to the router!!! It's always a tricky one, and can happen when even not on DV that the phone goes off, one of the reasons i would not go DV, then when joined EE dropped the landline but do miss it. Hope you get to the bottom of it.

@JimM11 i have tried plugging the phone and my BT test butt in on the Green phone port and still have NDT or blow as we called it, a simple power cycle on the hub returns the phone back to functional working but obviously annoying hence pushing for BT/EE to resolve. Thanks for your assistance re this issue.
