ISDN2 Digital Lines

Call Lines $30 per Month


ISDN2 is a basic rate ISDN service that allows a business to gain all the advantages of digital phone lines without having to commit to more than 2 call lines. They are ideally suited to businesses that require 2 to 4 call lines but don't have the necessary broadband infrastructure to activate SIP trunks.


PSTN Phone Lines

PSTN lines are the traditional phone lines mainly used by small businesses or as standalone lines for EFTPOS, Fax or delivery of a DSL service. These type of business phone lines are a basic telephone service that doesn't require a PBX phone system and is currently being phased out with the introduction of NBN and VoIP technology.
