With the introduction of VoIP or IP Phone Systems, this old-technology question is becoming all the more relevant in your final decision to purchase the right phone system today. A key system has telephones with multiple buttons that permit the user to directly select the telephone company’s central office phone lines. A key telephone system (KTS) is not a switch.
A PBX is sometimes referred to as a phone switch.
Key systems are usually found in small companies where few features are required and connected to your business phone system is able to have a button (called Line or CO Button) dedicated for each Phone Line that you have for calling out i.e. the local telephone company or CO lines.
When you press this Line Button on your phone, you are actually connected to one of the CO Lines from your phone company. Lets say you have subscribed for 4 business telephone lines from your local phone company then you will have Line 1, Line 2, Line 3 and Line 4 Buttons on your business phone. In fact this very feature of Having Line Buttons or Line Presence is a HUGE factor for most small businesses who usually have about 3 to 8 CO Lines and about 3 to 25 phones.
And what is a PBX Telephone System ?
In fact, the PBX Telephone System, in the practical sense, does not have the Line Presence feature or CO Line Button feature at all. Which makes the PBX System a bit inferior when compared to a Key Telephone System. Key Telephone Systems have all the features you will possibly need, whether you are a big business or a small business.
How do you setup a Key Telephone System as a PBX?
Simply because you do not have individual line buttons on an IP PBX Phone. A PBX or Private Branch Exchange, is a business phone system that doesn’t need the ability to have Line Presence on all its business phones or extensions. The critical point is that most of the IP PBX Systems or IP Phone Systems or VoIP Phone Systems DO NOT have the Line Presence feature.
