landline extension phone

[bmbmbm1]

Just had fibre 150 via eero6 installed and existing old wired house phone connected to digtal

voice adaptor So far all is well except that we have lost use of extension phone in bedroom which was also wired. Can I install a Panasonic kxt tgc digital phone or similar on eero6 and use it as my extension phone along with old house phone. If so how would I connect them so as they would be paired and work in conjunction.

Hi @bmbmbm1 I'd be tempted to start again with a dect phone, I recall they support 5 wireless extensions.

The new phone would have an answerphone included and connect to the digital Voice adapter.
