How many telephones can I have?

Equivalence Number (REN), which is used to calculate
the number of items which may be connected to any
one telephone line. Your BT Sonus 1500 has a REN of
1. A total REN of 4 is allowed. If the total REN of 4 is
exceeded, the telephones may not ring. With different

when the REN is less than 4.
Any additional handsets and chargers that you register
have a REN of 0.
