Computer to computer – when using VOIP, this technique is the most straightforward as it transfers digital data from one source to another without the need to convert back into analogue.

Some ATAs may require additional software, loaded onto the host computer. The ATA is used to convert an analogue signal to digital data, enabling the call to be carried through the internet.

ATA – this utilises a device called an Analogue Telephone Adaptor, that allows users to connect a standard to phone to a computer/ internet connection, that then uses VOIP.

A traditional phone handset is replaced by the interface of software – based VOIP phones or programs. Most VOIP calls will also let you use voicemail, make internet calls, or transfer tasks. The process of actually making a VOIP call doesn’t have to be that much different to a standard phone call and to make the call, hardware (headset, microphone, etc) is used, or a software – based VOIP phone is used. If the data needs to be decoded or decompressed, this is also handled by codecs. Audio voice signals are encoded as data and transmitted via IP, across a LAN (local area network) or online. The process of converting audio voice signals into digital packets is known as codecs. VOIP technology works by configuring analogue signals into digital data. VOIP calls can be made through various sources including a phone or VOIP adapter, within a computer, or through installations such as Skype, Google Hangouts and Facetime.

VOIP also refers to the technology used to convert voice into a digital signal, allowing individuals to make a call directly from a computer, VOIP phone, or data-driven service. For many it can provide a suitable solution for inter-business communication as well as other communication purposes, and as a service has become more popular, as it has the ability to be augmented with various different applications, working with the user in mind. VOIP stands for Voice Over Internet Protocol, and as a general term refers to the process of making phone calls through an internet connection as opposed to regular landline or mobile.
