ATA - Analog Telephone Adaptor
Also, ATA is one of the few acronyms we know of where 2/3 of the words are spelt differently based on where you’re from (Analog/Analogue and Adaptor/Adapter)!

ISDN - Integrated Services Digital Network
IVR - Interactive Voice Response
Generally speaking, the further a signal has to go, the longer the latency (there can be other delays such as poor configuration, but we’ll ignore those for now). An extreme example is satellite internet connections, which route your internet connection through a satellite in a geostationary orbit 35,000km above the earth. That means by the time your voice has reached whoever you’re talking to it has probably come 70,000km. Even at the speed of light, that takes about 1/4 of a second, which they experience as a moderate delay. Wow!
LNP - Local Number Portability
LNP sits alongside mobile number potability and local rate and freephone number portability (1800, 1300 and 13 numbers).
Know your rights! Not all providers will willingly allow you to port numbers away from them – but unless you were advised otherwise when you signed up for their service, they are not allowed to deny your request.
