Digital phone attached to full fibre broadband

[Bphone7]

I have a digital landline phone attached to my Wi-Fi router with an extension in another room.  These work ok. I also have another stand alone digital landline phone upstairs with an adaptor (from EE when changing to full fibre). This phone seems to have a mind of its own. It will ring upstairs but the phones that are  attached to the router don’t ring out. It will also occasionally ring out when I am actually using the downstairs phone, but  nothing happens when it is picked up.   Also if all the phones ring and I pick up the upstairs phone i can only hear on that phone and am unable to change to the downstairs phone as I used to (they are clearer). Anyone any ideas. Thanks

Let me get this clear! Is it that you have:

1. A DECT base station plugged into the phone socket of the router.
2. A freestanding DECT cordless handset in another room.
3. A handset plugged into a digital phone adapter upstairs?

1. Yes with answerphone, hands free and caller ID.

2. Yes. 2nd phone in another room is an extension of the main phone that’s plugged into the router 

3. Yes but it is a  completely separate older digital phone (not the same model as the other 2) though has caller ID. Photo of EE adaptor for this phone.

 Hope you understand thisThanks

I believe you can have simultaneous separate convos on DV. It must have something to do with that. Also there may be some grouping configurable by the EE app. You have effectively 2 phone "lines", the DECT system & the corded handset.

You say "as I used to".  Was that before you went digital? What was the set-up then? I have a similar set-up but on analogue. All phones ring on incoming call but only 1 type can pick it up. Conversely only 1 type can dial out at the same time. There is no association between them other than the incoming ringtone. Of course within the DECT system calls either way may be transferred between handsets.

All phones are digital and hands free. Before the phone was attached to the router I could receive a call upstairs and then pick up either of the phones downstairs (as the line was clearer) and replace the upstairs phone back on its base and continue my call. I  can no longer do that. If upstairs phone is picked up that’s the one I need to use.  Thanks for your input

Do mean they are all DECT or they all are meant to work on DV but not on a copper phone line?

What models are they?

The handset upstairs that is now plugged into the adapter, how was it connected before you got this router?

 this is the upstairs phone

 this phone is connected to the phone line on the router and its pair is in another room (came as 2 phones)

Both phones were previously connected to phone sockets one upstairs and one downstairs 

I’m not sure if  understand your first para correctly. According to the engineer who set the system up they should all work fine

I'm sorry, I got mixed up with my "digitals" 😞 .

What matters is whether your phone systems include a DECT base station or are just a freestanding DECT extension. The latter would need to pair with an incorporated DECT base station within the router but you have none of these.

 I'll revise what I think you have to:

1. A DECT base station (BT 3110) plugged into the phone socket of the router.
2. A DECT cordless extension handset in another room paired with 1. above.
3. A separate DECT base station (BT 2100) plugged into a digital phone adapter upstairs (it has no extensions).

However I can't see how you ever had any interaction between the 2 base stations unless you somehow detuned the upstairs 1 to become just an extension paired with the downstairs base station. Do they share a Phonebook/Contacts List or are they separate?

I still believe your issue may have something to do with the feature of DV that you can have simultaneous separate convos.

1,2 3 are correct.  Yes they do share contacts . Puzzling
