I could not find TP-Link Archer VR1600v Wireless Dual Band Gigabit VOIP VDSL/ADSL Modem Router listed amongst the models above.

It was fitted a week or so ago when my very reliable ASDL2_+ service was threatened with termination on Nov 12 by discontinuation of the copper-wire service.

The extensive phone-extension system I hade developed over the years had worked admirably - comprising one caller number display unit, one hands-free unit and  a number of analogue phones of various types, with and without memory facility. I had to replace two phones to enable the system to work. Also it would not work if ALL the phones were connected to just Phone1 socket, so I connected some to Phone2. But the functionality I have achieved is marred by the fact that, if I take a call on a phone connected to Phone1, but want to continue it on a phone connected to Phone2, I can not, because Phone2 gives a dial tone rather than a connection to my caller.

To clarify : when I say that the system does not work with ALL the phones on Phone1, what I mean, is that if a mobile calls my number, either it does not connect or drops out after one ring.

Best solution would be to have all phones on Phone1 - only two have the ringers activated - and to prevent the problem that calls from mobiles present.

Second best solution is to be able to continue on Phone2 a call made to Phone1.

Is help available ?
