Welcome to this user forum for BT Retail phone and broadband customers.

Where is your Panasonic phone plugged in?

It would seem highly unlikely that an entry system would dial out across the PSTN. Typically they connect to a dedicated handset with an entry button.

So are you saying that this Panasonic handset both made & received regular phone calls & also operated the door lock? If so, what model is it?

I'm confused, that is just a straightforward cordless phone. In what way does that connect with your door entry system. I can't see that there can be any connection between your door system and a public phone service either analogue or digital.

Some older phones need an extra "ring" wire to make the ringer work.

Plugging a microfilter into the socket on the back of the Smart Hub 2, and plugging the phone into the phone socket on the microfilter, emulates the "ring" wire.

The microfilter has an internal capacitor which passes the ringing current to the "ring" wire.

This is worth a try thanks.The phone worked ok as ahome phone and worked with the door entry system ok until plugging it into the router may be.I read somewhere i should have a micro filter in line anyway.

This sounds more positive thanks

The microfilter would not normally be used for that purpose, but the internal capacitor help in this case. The alternative would be to make up your own lead, with an inline capacitor.

All modern phones only need two wires, as they have an internal capacitor to isolate the 50V line voltage.

I really still don't understand how the entry phone rings the house phone. If all other calls to the phone work ok, it certainly won't help putting a filter in place.
