Amplicomms BigTel 1582 Big Button Cordless Phone with Answer Machine, Twin Handset

Is this phone compatible with my setup?

If you have a router with a phone port like the diagram below*, then you'll easily be able to plug in the phone cable provided with the phones (or with the RJ11 cable provided with your router).

Alternatively, if your router looks like the one below, without a phone port, then you'll need an adapter like the one pictured to allow you to connect up your phone.

*Please note the configurations of your router may look different, however you should still be easily able to locate if there is a phone port or not.
