    Whether you are looking for your first phone system, or upgrading an old one, it can be difficult understanding the types of lines that are available and the ever changing jargon used to describe them.

    PSTN lines: PSTN (Public Switched Telephone Network/Analogue), is a traditional land line, as per your home line and used for broadband. Features include caller ID and call diversion, but it is limited to a single telephone number that can be used on a single or over multiple lines.

    ISDN2: ISDN2 (Integrated Services Digital Network/BRI). As suggested in the name, the line starts with 2 channels and further pairs of channels can be added. Features include:

  • DDI (Direct Dial) numbers, ordered in blocks of 10
  • Transfer calls to an external number
  • Caller ID
  • Telephone systems and cloud solutions:

    ISDN30: ISDN30 is also known as the (Primary Rate Interface/PRI). A digital network similar to ISDN 2, with the same features that has the added advantage of between 8-30 channels on a single connection, but multiple circuits can be added to give 60, 90 or even 120 channels. It is a perfect solution for a large business with multiple line requirements.

    VoIP/cloud technology: VoIP (Voice over Internet Protocol) service runs over an internet connection, and can have either SIP lines or a hosted solution running over it. The beauty of this technology is it only needs one physical PSTN line and a broadband and enables you to link multiple sites. Phone numbers can be pointed to any location home or abroad.

    SIP: SIP (Session Initiation Protocol) is a line that connects via VoIP to a phone system. Features include:

  • Caller ID
  • DDI numbers
  • Quick programming changes done on-line
  • No physical lines
  • Home workers can look like they are in an office environment
  • Reduce monthly costs
  • Call processing
