Voice over IP converts your voice into a digital signal, compresses it and sends it over the Internet. A VoIP service provider establishes the call between all participants. At the receiving end, the digital data is decompressed and converted into the sound heard through the handset or speakerphone. On the other hand, VoIP phones do not have "lines" in the traditional sense.
Instead of being tied to a phone number, each "line" on a VoIP phone is tied to a SIP address, or user account. Depending on your phone model, your phone may be able to handle multiple user accounts simultaneously. This means that you can receive calls from multiple accounts and different phone numbers on your VoIP phone. VoIP phone service (sometimes called broadband phone service or digital phone service) is a phone service that works using your high-speed Internet connection.
These services allow you to make phone calls using your regular phone, an application on mobile devices or a softphone client on a computer (through a headset). Unlike traditional landline phones, VoIP uses your phone or computer to call the number over the Internet. The call is converted into data packets and sent over the Internet rather than over the copper wires that make up a standard PSTN network. Using a mobile VoIP phone with access to a WiFi hotspot can also reduce a mobile VoIP phone user's costs by avoiding the operator's expensive 3G service.
Mobile phone users can use the mobile VoIP service on their phone with the addition of mobile VoIP software. When the people who work for your VoIP phone service keep employees happy, you receive superior service. A VoIP phone offers the same basic service as a regular phone, the ability to make, receive and manage phone calls. If you are concerned about this, you may consider VoIP as an additional phone service rather than an alternative to a traditional phone line.
Some mobile phone users take advantage of mobile VoIP telephony service to eliminate their voice plans. VoIP - also known as Internet telephony, IP telephony or broadband telephony - is a way of making phone calls that, believe it or not, does not use a phone line. Some voip services only work through your computer or a special VoIP phone, while other services allow you to use a traditional telephone connected to a VoIP adapter.
