If you are looking for a multi-line phone, but you don’t want to buy an expensive phone system cabinet, then a great alternative is what is called a non-KSU phone. A non-KSU, or non Key System Unit phone, is basically a multi-line telephone with many of the same features as their KSU counterparts. A non-KSU phone makes sense if you are looking for a reasonably inexpensive way of getting a professional-grade system for your home or office.
The most popular Multi Line phones are made by Panasonic and AT&T. There are several options when choosing these convenient phones. The first option is a two-line corded phone. These are usually available with caller ID, answering machine, and can sometimes expand up to 8 phones within the network. So if you have a house or office with 2 incoming lines and you need up to 8 phones, these phones would be a great fit for you. There are also 4 line corded phones that come with many features such as caller ID, answering system, intercom, conferencing, and much more. You can put as many as 16 of these 4 line corded phones in one location; meaning you can have 16 phones and 4 incoming lines.
Other options included getting 2 line or 4 line cordless phones. These multi line cordless phones have great capabilities such as intercom, caller ID, conference, and more. The Panasonic KX-TG6700B and KX-TG4500B are the most popular of the cordless phone systems. The KX-TG6700B is a 2 line cordless system that can grow up to 8 handsets total. The KX-TG4500B comes with 4 lines. The cordless phone system comes with a corded base unit and 1 cordless handset. The phone system is capable of growing up to 16 cordless handsets.
