A:AnswerYes a belt clip is included that can be attached to each handset. This phone system works great. The best feature is Link2Cell where you can pair your cellphone to the base and then make and answer you cell phone calls on all of the handsets.
A:AnswerBecause Link2Cell allows you to answer and make calls on your cell from any handset. However, it does not work to answer the home phone on your cell unless you call forward your home phone calls to your cell. I do this and can get all home phone calls on my cell even when not at home. The call forwarding is done on the Xfinity system as it is my home phone provider.
A:AnswerThe phone is capable of using the remote access of voice mail. I do not use the feature so i can not tell you how it works exactly. But it was simple when i looked at the manual. Fyi if you google the model number you can get the instruction booklet and it will provide all the details needed.
