What is a POTS codec – and why is it called POTS?
A POTS codec allows live connections – in the same way as an ISDN codec – but is designed to work over a standard telephone line. Audio is compressed and then sent and received as data over the phone line to offer a broadcast quality connection. POTS codecs can be used in areas where ISDN service is unavailable, or where you just need to get on air fast! As to the name: In telecom engineers lingo, POTS stands for Plain Old Telephone System.
