How many telephones can you have?
All items of telephone equipment have a Ringer Equivalence Number (REN), which is used
to calculate the number of items which may be connected to any other telephone line.
Your BT Freestyle 7110 has a REN of 1. A total REN of 4 is allowed. If the total REN of 4
is exceeded, the telephone may not ring.
With different telephone types there is no guarantee of ringing, even when the REN is
less than 4.
