The RingCentral VoIP phone system, called DigitalLine, works much like how a standard telephone works. However, instead of date being sent through phone lines, communication happens through the Internet. By using Voice over Internet Protocol, or VoIP, calls are sent to and from different Internet connections, providing efficient and affordable communication solutions to subscribers. The DigitalLine VoIP system is fully integrated into any RingCentral Mobile account, so there is no need to change numbers. Users may choose to facilitate calls through the Call Controller and use it as a softphone. All you need is a headset, and you are ready to take calls right on your computer. Another option that RingCentral subscribers can use is the Analog Telephone Adapter, or ATA. This device is used to convert standard phones into digital phone units which can be used for VoIP calls. RingCentral also has digital IP phones which can be ordered through them. There are a lot of advantages to using VoIP for your business calls. First, calls are more affordable. The Internet is not reliant on physical distance, so long distance calls are charged local rates. Moreover, it provides a more streamlined communication to businesses, eliminating the need for a separate phone subscription.
