Business VoIP is gaining popularity as many companies continue to integrate its use in operations. This technology has many advantages, including greater scalability and substantial potential savings. However, it also bears its share of limitations. For instance, it requires the availability of a reliable high bandwidth internet connection. So what is a VoIP phone system?

What Is a VoIP Phone System?

VoIP or Voice over Internet Protocol lets you make voice calls over the internet or LANs (local area network) instead of the typical mobile network or landline. Popular apps like Viber, Skype, FaceTime, LINE, Facebook Messenger, and WhatsApp use VoIP to facilitate calls. Many businesses adopt the technology due to its convenience, low cost, and added advantages over regular phone service. 

VoIP allows you to make calls anytime, anywhere, and you only need a reliable internet connection and an internet-enabled smart device with a speaker and microphone. VoIP technology converts analog voice signals into digital packets of information transmitted over the internet connection. VoIP digital signals are then reconverted into regular phone signals at the destination. 

VoIP is transforming into full-featured unified communication hubs handling all communication forms, including voice calls, web conferences, voice mail, faxes, and email. Different VoIP types include integrated access, Hosted IP private branch exchange (PBX), session initial protocol (SIP), and managed IP PBX.

VoIP Advantages and Disadvantages

VoIP has several benefits, especially for a business that aims to reduce costs and improve conference call quality. However, as with every piece of technology, VoIP has its disadvantages limiting its use. 

Advantages of VoIP

Reduced Cost

Adopting VoIP systems can help an organization achieve significant cost savings. For example, it can help you save on your phone bills by more than 50%. However, the cost savings will vary depending on the VoIP service you choose and your business needs. Nevertheless, VoIP can save on costs either directly or indirectly.

Direct Cost Savings

PBX Cost

A private branch exchange (PBX) is an on-site physical piece of hardware that connects several landline phones in an organization and costs a lot of money. The cost of installation of on-site PBX is very high. VoIP phone systems

The SIP Trunk allows the exchange of voice services and maintains your current office hardware. You can activate SIP Trunking instantly, and it is easier to manage. 

Eliminating Wiring Charges

VoIP systems help eliminate charges associated with extra wiring since they allow both data and voice on the same channel. In addition, they are full-duplex, meaning that they can send data and voice concurrently and only require one Ethernet cable to connect. This also means that an office will save costs on altering the building’s electrical wiring. 

Reduced Calling Expenses

A business can spend a significant amount of money on phone systems and integration expenses throughout the year. An organization will save costs by utilizing VoIP calls since they are cheaper than the traditional circuit-switched or public switched telephone networks. This is due to the reduction of data carriage costs, making VoIP affordable. In addition, there has been an increase in internet speeds, and data charges have been reduced significantly.
