Business VoIP applications ensure phone calls don’t hog a ton of bandwidth and that calls are clear and crisp. That is, they compress data and move it quickly. The success of a codec depends on its compatibility with different devices. If your VoIP provider has multiple data centers, reliability is a non-issue for a vast majority of phone calls. You might encounter some VoIP problems since calls travel over the internet. VoIP codecs determine the call quality and latency in a conversation since the call takes place through the internet. In the case of a VoIP codec, it converts analog voice signals into digital packets or a compressed digital form for transmission and then back into an uncompressed audio signal. For instance, codecs determine the quality and bandwidth you need to watch videos on YouTube or Netflix. Practical examples of codecs include image capture (JPEG), encryption software (AES), streaming media (H.264), and music and audio recording software (MP3). The word codec is a portmanteau of two terms: Compression and Decompression.Ĭodecs are the reason why you can download a movie in minutes, not hours. VoIP codecs use either proprietary or open-source algorithms. Read along as we discuss what a codec means, along with how you can select the right codec for your company’s VoIP phone system.Ī VoIP codec is a technology that determines the audio quality, bandwidth, and compression of Voice over Internet Protocol (VoIP) phone calls. It’s all possible because of VoIP codecs. Thanks to Voice over Internet Protocol (VoIP), today’s phone calls are crystal-clear and only need an internet connection.
