VoIP Network

What is a Codec?

Codec is a portmanteau of “Compression Decompression”. A codec defines the process by which audio is compressed and encoded, and then decompressed and played.

A codec determines the quality of audio as it is played from a computer.

The PSTN and most standard definition calls are made in G.711u, HD quality calls usually use G.722.

See why 100,000 companies trust Nextiva for VoIP service.
