WHAT ARE THE TYPES OF VOIP ADAPTER AND HOW IT WORKS?
VoIP adapters are also known as analog terminal adapters and they used for the purpose of converting analog voice signals into digital IP packets. Also, these adapters can convert digital IP packets into analog voice streams.
How VoIP Adapter Works?
A VoIP adapter bridges the gap between an IP network and a desktop telephone or PSTN. A VoIP adapter will convert voice traffic into data packets with the help of destination network or device.
In this way, it reduces the need for purchasing new instrument that supports VoIP technology. The VoIP adapter also provides other subsidiary functions including: the dial tone, caller ID, identifying touchstones and other essential functions that are required for the VoIP call.
The VoIP adapter performs its function with the help of specific VoIP protocol and audio codec. A VoIP protocol and codec is essential to let your VoIP technology work in accordance. Your codec and VoIP protocol should be compatible with your VoIP phone service. In addition, the quality of your calls, highly depends upon the protocol and codec which you are using.
In this whole scenario, the VoIP protocol helps to communicate with web server and codec performs the function of changing audio signals into digital data.
In case, if you are using VoIP adapters for business purpose then you must identify that what protocol is supported by your VoIP provider. Typically, the most common VoIP protocol is SIP that is session initiation protocol. Similarly, the most applied codecs are G.711, G.729 and others are also available.
If you get complimentary adapter in the purchase price by the VoIP vendor, it’s mostly preconfigured with the correct settings. In case, if you purchased it separately, you can access the web configuration via computer.
