Dialing is not possible. Is the extension phone connected? Check the telephone line jack, the extension phone

jack, the wall jack, and any extension adapters to make

sure that all connections are secure.

You cannot talk to the

other party.

Did you dial using the speaker? When you dial using the speaker, you will be able to

hear the voice of the other party, but he or she will not

hear your voice. Use the extension phone. (When the

extension phone is not installed, you cannot talk to the

other party.)
