What Is an IP Phone?

VoIP phones make and receive calls through an internet connection. Due to their low-cost nature, internet phones are cheap alternatives to traditional landline phones because they can work on any computer with a sound card.

Function

IP phones are referred to as internet protocol phones because instead of using plain old telephone system (POTS) for receiving and placing calls, they connect to the internet using broadband. In comparison, VoIP phone service is considered more efficient compared to POTS.

Internet Phone Benefits

  • Unified Platform

The ability to converge technology platforms makes Internet phone service more beneficial than traditional phone systems. Your provider probably designs applications that can work with voice systems, Internet, and computer networks. For instance, you can save voice mail messages as data on email because VoIP systems makes it possible to mirror your office phones on computer desktops for use anywhere with an Internet connection. Integrated or unified communications is technology that coordinates mobile devices, office phones, and computers to work together. You can achieve much more with VoIP systems than you can with traditional phone systems.

  • Cost Savings

Internet-based phone technology comes with more cost saving features than traditional systems thanks to the ability of your phone provider to deliver both phone and internet on the same cable, which reduces communication costs. Communicating over long distances using an Internet phone costs less than traditional phones because Internet phone billing is not based on the distance between the caller and the receiver. In addition, Internet phone systems make it possible for you to save on interoffice communication because the VoIP system remains part of the network regardless of location.

Types of Internet Phones

Your Internet phone provider has two main types of VoIP systems: Software based and hardware based. Many ISPs provide a wide range of hardware for these services including adapters that allow regular phone systems in your house to be used as internet phones. In addition, VoIP software solutions allow phone calls through applications like Skype from computers with sound cards.

Considerations

Despite their versatility, VoIP do not support 911 calls. Therefore, it is recommended to maintain both IP phones and traditional phone systems for emergencies. Hackers can also use spyware to access your VoIP phone system and eavesdrop on your conversations using “packet sniffers” or direct expensive phone calls through your internet connection. Your business internet phone system must, therefore, integrate firewall security with all networks to enhance security.

Internet phones deliver voice communication and phone service through voice over Internet protocol (VoIP) technology. These phone systems have many advantages over traditional phone systems and have become increasingly popular in many homes and businesses. VoIP systems are affordable and have a wide range of applications. This service can be used for both voice and video communication provided there is an Internet connection.
