FAQs

Questions, answered

The things locals ask us most.

What communications services do you offer?
Reliable Computers sets up and supports business phone systems for St George and Sydney businesses: VOIP/hosted phones, Microsoft Teams calling, number porting, call handling and the network and connectivity behind them. We’ve delivered business communications since 2009.
What is a VOIP phone system?
VOIP (Voice over IP) runs your business calls over the internet instead of traditional phone lines — lower line rental, easy to add or remove users, and you keep your numbers. Reliable Computers designs, installs and supports VOIP for Sydney businesses.
How much does a business VOIP system cost?
VOIP is typically billed per user or handset per month with low call rates — usually well below traditional PSTN/ISDN line rental. Reliable Computers scopes and quotes your system up front after looking at your call volumes and team size. Call 1800 753 991.
Can you set up Microsoft Teams as our phone system?
Yes. As a Microsoft 365 specialist, Reliable Computers configures Microsoft Teams calling so your team can make and take business calls from Teams on desktop and mobile — chat, meetings and calls on one platform.
Can we keep our existing phone numbers?
Yes. Number porting moves your existing business numbers across to the new VOIP or Teams system, so customers still reach you on the same number. Reliable Computers manages the porting to keep disruption to a minimum.
Can staff make business calls from home or mobile?
Yes. VOIP and Teams calling let staff make and receive calls from anywhere — desk phone, laptop or the mobile app — using your business number, which is ideal for hybrid and remote teams.
Is VOIP reliable for business calls?
With the right internet connection and configuration, yes — call quality is excellent and uptime is high. Reliable Computers makes sure your network and bandwidth are set up for clear, dependable calls, and can add failover so calls keep flowing if your internet drops.
Will my office network handle a phone system?
It needs to be set up correctly — voice traffic prioritised, enough bandwidth and a solid connection. Reliable Computers reviews and configures your network and business internet so your phones and cloud apps run smoothly together across Oatley, the St George area and Sydney.
Can you integrate our phones with our IT and Microsoft 365?
Yes. Because Reliable Computers can manage your whole IT environment, your phone system, Microsoft 365, email and devices all work together — one local team and one point of contact, with no finger-pointing between vendors.
Why choose Reliable Computers for business communications?
An award-winning MSP (CRN MSP of the Year 2024), established in 2009 and rated 4.8 stars from 232 Google reviews, Reliable Computers is a local St George team at 1/89 Mulga Road, Oatley NSW 2223 that sets up and supports your VOIP, Teams calling and connectivity with fixed, predictable pricing.
