When people mention voice over IP (VoIP) most are thinking about a business phone service rather than home phone. After all, businesses run data networks and that's what VoIP needs to operate. But now that the majority of homes have an Internet connection, that means they're also running a data network, just usually a smaller and simpler one than you'd find at the office. If you're careful about what you buy, you can take advantage of VoIP's key benefits, which include far more features and a much lower price tag than an old fashioned landline.
Now that so many people are working from home, keeping your business' voice communications organized and centralized can be tricky. Fortunately, that's where cloud-served voice over IP (VoIP) providers can shine. With cloud VoIP (sometimes called a cloud PBX system), you can move direct extensions to new geographical locations simply by clicking a mouse. Devices can also change with similar ease either with a software download or simply by re-configuring call forwarding. With many of these systems also adding a wide variety of team collaboration features, cloud VoIP is probably the best COVID-19 investment a business can make.
It's also possible to switch a call from a mobile device to a desktop line or vice versa. Business products generally offer several pricing levels based on the number of lines needed, ranging from approximately $20 per line for large organizations to $35 per line for smaller groups. Even from an administrative perspective, you should be careful, however, when migrating to a new phone system. Whether you're an individual just buying a new land line or a business moving from an old-style PBX system, or even just switching to a different VoIP provider, the process should be approached carefully and only after thorough planning.

Not every internet connection is VoIP ready, so before you sign up, make sure that your line will provide you with the level of VoIP speed and service you need.

The quality of your connection can potentially impact the clarity of your calls, so pay close attention. 
VoIP has drastically reduced the cost of communication by sharing network infrastructure between data and voice.[48][49] A single broad-band connection has the ability to transmit more than one telephone call. Secure calls using standardized protocols, such as Secure Real-time Transport Protocol, as most of the facilities of creating a secure telephone connection over traditional phone lines, such as digitizing and digital transmission, are already in place with VoIP. It is necessary only to encrypt and authenticate the existing data stream. Automated software, such as a virtual PBX, may eliminate the need of personnel to greet and switch incoming calls.

Few things in life are set in stone, and the same should be true of your VoIP plan. It’s wise to find a plan that is scalable and which you can easily expand if need be. You’ll want to know if you can break your contract early if you find a better deal elsewhere, or if you can easily switch plans with the same company in order to take advantage of more features, or to get rid of some you don’t need. 

Some form of call center capability is often available, though many times either as a different product version or simply a higher pricing tier, so be careful before you assume you'll be getting those features. These capabilities are meant to support large sales or service desk staff and their need to route and process a relatively large number of incoming customer or user calls. That means complex menu trees, an auto-attendant for routing, and service queues. You'll probably find you need interactive voice response (IVR) capabilities, and that should be backed up by support for a live operator or some other type of human intervention.

These look and work the same as a regular phone aside from the initial setup process, which will require making sure the phone is connected to your Internet router in some way and then configured to access the VoIP provider's service from there.
