Public Switched Telephone Network is the most commonly used phone line in Australia. It is a basic telephone service line that provides your organisation with landline telephone connectivity, a telephone number, and other additional services.

PSTN Services are suitable for:

  • Small organisations
  • A phone line for voice, fax, EFTPOS, and ADSL internet connectivity


Integrated Services Digital Network is a service connection that allows Voice and fax networks to be transferred concurrently across Australia using digital technology. It is a business grade service with functionality to support 2-30 simultaneous calls and advanced fault tolerance.

ISDN Services are suitable for:

  • Organisations that require individual extensions for users and/or functionalities to manage multiple calls simultaneously
  • Organisations with call conferencing requirements
  • Organisations with higher call volumes

Organisations that require more advanced
telephony features



SIP or Session Initiation Protocol which is the basis of SIP Trunking, is the standard communications protocol for voice and video in a Unified Communications (UC) solution across a data network.SIP Trunking eliminates the physical connection to a phone company. There are no hardware, wiring, or circuit boxes to maintain for connection to the PSTN (phone service provider). Reducing multiple phone lines into a single point of entry drastically reduce charges for incoming lines and the costs associated with the maintenance of those lines.

The cost savings and communications benefits of SIP trunking are substantial.

If your business is experiencing:

  • High monthly phone bills
  • Costly charges for incoming phone lines
  • Long distance charges
  • IT and maintenance fees
  • Constraints of limited communications technology


We offer flexible and scalable technology through premium network infrastructures, allowing customers to implement and manage an effective telecommunications solution.

Whether you’re looking for a small business internet connection, or an advanced multi-site network offering, Emerge Communications has the capability and experience to set up the optimum infrastructure for your business.
