Cloud Phone Systems: PBX & VOIP

Love your phone system again! With hosted PBX, you no longer deal with fixed line cost and limitation. Imagine the flexibilities you have with your emails these days, now apply the same thinking to your inbound phone calls! Half the price and triple the functionality plus complete freedom of location.

What we do

Our full functionality VoIP systems are of the same call quality as conventional PBX phone systems. We support your infrastructure setup too.


Seamless and hassle-free onboarding while keeping your existing numbers without service disruption. We can also come onsite!


Access to free conference call facilities, time switches, tone menus, call queues, voicemail to email, fax to email, international numbers from $4p/m.


Not only does hosted PBX improve business communications but in most cases there are savings from 30% to 60%


Our VoIP Services

Extensions / Phones: Number of extensions allowed on the plan, i.e. handsets connected to the PBX. Simply upgrade to the next plan if more handsets are needed.

Phone Numbers: Standard 10 digit Australian phone numbers, i.e. 02 8188 7557. There is no differentiation between VoIP numbers supplied by us or current landline numbers transferred in. Porting cost for existing numbers from any Australian Telco (including but not limited to Telstra, Optus, Skype, etc) is $60 once off for a single number or $220 once off for a set of numbers.

Lines: As with conventional systems, a line represents the ability to make a call. 10 lines means 10 users can make a call at the same time.

Mobile Rate: Cents charged per minute for calls made to Australian mobile phones. No flagfall applies on call connect. Charges are applied per second, NOT in 30 or 60 second blocks.

Monthly Charge: The system works with a top-up account that needs to remain with a positive balance at all times. A VISA or MasterCard is on file in the control panel and tops up the balance by a set amount ($10 to $100) whenever a threshold is reached (usually $5 balance). A full statement / tax invoice is issued at the first of every month for the last month and emailed to the account holder.
