Hi,I bought mentioned model answering system telephone sets, but I cannot get the answering system facilities. If someone calling & leaving messages at that time I cannot hear & also I saw handset showing message waiting, but if I press the play button on base its mentioning no new messages. That's means base not working properly. I change the total sets from store three times, but still I am getting the same error. Could you please explain briefly how can I setup this answering system? Am I missing some things?RegardsMd. Ziaul HoqueE-mail-hoque@rogers.com
