ATA - Analog Telephone Adaptor
An ATA or Analog Telephone Adaptor is a device that converts analog voice signals from a non-VoIP based telephone, to digital signals which can then be transmitted over the internet.
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
A CDR or Call Detail Record documents all of the calls that have passed through a telecommunications providers infrastructure. Aatrox Communications providers a CDR at the end of each month to view details of all calls made, which comes in the form of a CSV file.
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
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.
