how does voip work?

Unlike landline phone systems that are limited to a single desk phone in your office, VoIP allows you to make and receive business phone calls from your laptop, tablet, regular smartphone (using an app), and even VoIP-compatible office phone devices. Although VoIP may sound quite technical and complicated, the main thing to understand is that VoIP is a more efficient method of transferring data during phone calls.

Unlike landline phone systems that are limited to a single desk phone in your office, VoIP allows you to make and receive business phone calls from your laptop, tablet, regular smartphone (using an app), and even VoIP-compatible office phone devices. Although VoIP may sound quite technical and complicated, the main thing to understand is that VoIP is a more efficient method of transferring data during phone calls. To call someone using VoIP, you need a SIP-compatible desktop phone or VoIP calling application, which means you are assigned an IP address so that calls can be made from your network. A typical VoIP setup involves a desktop phone and a SIP server, which is usually a VoIP service provider.

Major carriers, such as AT&T, are already establishing VoIP calling plans in several US markets, and the FCC is taking a serious look at the potential ramifications of VoIP service. Since VoIP is a relatively new technology, this compatibility issue will remain a problem until a governing body creates a universal standard protocol for VoIP. Therefore, endpoints, such as VoIP phones or softphone applications (applications running on a computer or mobile device), will connect to the VoIP service remotely. As VoIP grows in popularity in enterprise markets due to LCR options, VoIP needs to provide a certain level of reliability in handling calls.

The technical details of many VoIP protocols create challenges in routing VoIP traffic through firewalls and network address translators used to interconnect to transit networks or the Internet. VoIP is the technology that converts voice into a digital signal, allowing a call to be made directly from a computer, VoIP phone or other data devices.
