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)!
CDR - Call Detail Record
DID - Direct Inward Dialing
Bandwidth is very important in achieving high-quality VoIP performance – have a look at our FAQ for more detail on your bandwidth requirements.
IP - Internet Protocol
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.
PBX / PABX
A PBX is a Private Branch Exchange, and a PABX is a Private Automatic Branch Exchange. To understand what a PBX is, we’ve got to look back – way back. Before computers, a phone call involved speaking to an operator who would manually plug in wires to link up your phone with whoever you were calling. Once the circuit was completed, you had a phone call. These operators worked in rooms called PBXs, and they existed in cities, large companies, suburbs, and so on. Once computers – or more specifically electronic switching – entered the picture, these PBXs were able to be automated, and these new automated systems became known as PABXs. Over the years plenty of additional technology has been introduced such as conference calls, intelligent routing, and so on.
These days, a manual PBX is something we might see in a museum – so there’s no real difference between PBX and PABX and the terms are used fairly interchangeably.
