A:AnswerWe recommend you the Panasonic KX-TGM450S Amplified Cordless Phone with Answering Machine. This will give you much more flexibility to adjust the volume.
A:AnswerNo.
No beeps or lights.
It is kind of an inconvenience because the phone it replaced had lights when New message was there.
Otherwise great phone.
A:AnswerYour greeting message can only be heard on the other side of the Phone, by the person who is trying to contact you. With Link2Cell feature you can connect 2 Cellphones (not at the same time) to your Phone System in order to make and receive landline calls by using them.
