Voice over Internet Protocol (VoIP) adapters are one of the most frequently adopted products globally. As individuals and organisations transition from conventional phone service to VoIP, they have concerns about VoIP technology, equipment, and solutions and one of these are understanding how VoIP Adapters work.
A VoIP adapter, also referred to as an analogue telephone adapter (ATA) or a VoIP modem, switches voice signals from phone lines (analogue calls) to digital signals. These are then processed and divided into packets for transmission via the internet. An FXS port on conventional VoIP adapters connects to analog telephones. The VoIP adapter then connects to your LAN via an internet wire and an RJ-45 connector. An FXS port links your analog fax machine to your VoIP phone system, FXO port lets you combine analog telephone lines with your VoIP phone system, whilst the RJ-45 Port is the Internet interface that links up your LAN to your VoIP adapter.
To use an adapter negates the necessity to buy new equipment that is aligned with VoIP phone systems. Caller identification, the dial tone, touchstone recognition, and all other signalling operations necessary for a VoIP connection are all examples of ancillary services of VoIP adapter.
To accomplish tasks, the ATA relies on a specialised VoIP protocol and audio codec. Audio signals are converted to digital data by a codec using the VoIP protocol and the remote web server codec.
Some people don’t care about protocols and codecs since their VoIP provider will either supply one for them or give a choice on their website that is known to operate with the service. But It is important for business users to understand which protocols and audio codecs are supported by their operator. Why? Because the quality of the calls and the amount of bandwidth used are determined by these.
