A VoIP phone system lets residents and businesses manage phone calls via the Internet in a much more efficient manner than through traditional systems.
VoIP phone systems are widely used because they are very affordable communication tools. The Internet is a faster network than the traditional phone networks, so it can handle large volumes of calls with less equipment at a fraction of the cost.
Even more, phone calls in the continental United States are free in most cases, depending on which VoIP service provider you select. International calls typically cost as low as 1¢ per minute.
A phone system is not limited to telephones—users can also use softphones, mobile devices, and other telecommunication devices to handle phone calls.
At the most basic level, systems allow a phone to connect to only a limited number of lines through the public telephone network. Without a VoIP system, each phone would need to separately connect to the public switched telephone network (PSTN). Now, each phone has its own line that can handle multiple calls at once.
If you want to make a phone system upgrade—from a traditional to a VoIP-based system—but you don't want to replace your equipment, you can opt into SIP trunking, which converts analog signals to digital ones for Internet calls.
Benefits of a VoIP Phone System
VoIP phone systems provide reduced infrastructure costs and low long distance rates, as well as advanced and scalable functions that enhance employee productivity and customer service.
These benefits make VoIP a smart choice for businesses using PBX phone systems. IP phone systems will save you up to thousands a year compared to traditional phone services.

Types of Phone Systems
There are different types of phone systems that fit various telecommunication needs.
A keyless system, or a KSU-less system (key system unit), is a very basic system for organizations or businesses with fewer than 10 users. A keyless system is an inexpensive PSTN phone system that is simple to set up and use. Also, it is a portable phone that can be easily moved when relocating offices. A disadvantage to using this type of system is that there are no advanced features to manage frequent, large volumes of calls. For instance, users cannot answer a phone call in the middle of another call.
A key phone system, or KSU system, is most commonly used by businesses that need 5 to 50 extensions with basic business telephony needs. Each line has a dedicated line button, which indicates the status of the phone.
A PBX (Private Branch Exchange) system also manages large volumes of phone calls between internal and external users. This system is designed for at least 5 users and up to several thousands of users working from different locations.
However, a PBX phone system does not have the line presence feature that key systems have. PBX systems cannot be set up as key systems, but it is possible to set up key systems as PBX ones.
A PBX phone system is commonly used by medium to large businesses, especially those that need to use more than one phone line to connect to the external, public system. As a result, this type of system will definitely have these features: conference calling, call routing, and auto attendant.
Small businesses can use a hosted PBX system with all the features of a large business PBX for a very inexpensive price, thanks to VoIP's affordability.
Also, an IP PBX system is a VoIP PBX service that converges voice and data networks into one system for cost-savings and functionality. IP PBX systems are on-premise phone systems, which is unlike offsite PBX systems that are either hosted or cloud ones.
