Compared to the PSTN, the average cost of VoIP is much lower. VoIP is a type of phone technology that allows users to make and receive phone calls over the Internet. Using VoIP, you can eliminate the need for an old telecommunications system or reimbursed cell phone plans.
If you are a small business, it may be worth considering a VoIP solution. VoIP is especially attractive for businesses that need to make international calls. Many VoIP providers offer free international calling. Also, the phone is a cloud-based system, so you don't need to worry about maintenance or hardware.
The VoIP service provider you choose should have products and features designed for small business owners. If you're a large enterprise, you may want to hire a vendor that can set up and maintain your system for you.
The real total cost of ownership includes maintenance and support, software licenses, subscription fees, hardware if needed, and other related services.
VoIP service providers will outline features in their plans. Some will offer free calls to landlines or another computer. Some will also offer free calls to other VoIP users. You may also need to pay a one-time fee to port your phone number.
