How many telephones can you have?

All items of telephone equipment have a Ringer Equivalence Number (REN), which is used

exceeded, the telephone may not ring.
With different telephone types there is no guarantee of ringing, even when the REN is
less than 4.
Only use the approved power adaptor and charger.
Only use approved AAA NiMH rechargeable batteries.
