PSTN Phone Lines – Telstra

One of the first services you think of getting set up when you are starting a new business, or moving or expanding an existing business, is your fixed line phone service.

These days, however, there’s a lot more to it than just calling Telstra and getting them to install the traditional analogue phone line. There are analogue phone systems, digital phone line systems, and a range of options to consider such as Group Directory Numbers and Direct Indial and more.

PSTN Phone Lines - (Basic Access)

PSTN (the Public Switched Telephone Network) is the traditional analogue phone system, commonly used in businesses around Australia. PSTN runs on copper pair cables into your building. A & B Communications offers PSTN phone line services via Telstra’s Basic Access service.

PSTN can be used for phone lines, fax lines, EFTPOS lines and Internet access. If your business requires more than one (1) line, PSTN phone lines can be grouped together via a feature called “line hunt”. This means you have a main advertised telephone number, and when this line is busy it automatically cycles additional calls to the remaining auxillary lines, which feature line hunt. This would then be shown on your phone system as Line 1, Line 2, Line 3, and so on.

Benefits of PSTN phone lines:

  • The service is readily available in most areas of Australia, offering connection to a constantly growing service, which currently reaches 97 per cent of Australian homes and businesses
  • Available with a free standard listing in the White Pages telephone directory and in a range of pricing options
  • Offers a 24 hour, seven day fault reporting service, so you can report faults at any time

Disadvantages of PSTN phone lines:

  • Unable to transfer out to mobiles smoothly unless you pay for an additional service know as Business Links
  • More expensive line rental than digital lines
  • Unable to have direct in-dial to your desk for outside callers
