IP
Internet Protocol is the way in which information is passed across the internet.

Public Services Telephone Network
PSTN is the way that we have always communicated by telephones that transfer the voice signals over copper cables.
Private Automated Branch Exchange
PABX allows a single telephone number to offer multiple lines to outside callers while providing a range of external lines to internal callers or staff. A company often has a general telephone number into a switchboard that can divert the call to users across departments and locations.

Analogue
Generally seen as the ‘old fashioned way’ of sending information or making telephone calls. The internet and computer systems are in a digital format which changes your voice end email into a series of ones and zeros rather than travel via cables.
