Frequently Asked Questions

Why is my Telstra bill so high?

Most Telstra business plans charge separately for line rental ($30-55/line), national calls, and calls to mobiles. A 5-line business can easily pay $300-500/month before call charges. VOIP bundles all of this into one per-user price, typically $20-30/user/month with unlimited local, national, and mobile calls included.

Will I lose any features switching from Telstra to VOIP?

You will gain features. Most Telstra business phone plans do not include voicemail-to-email, auto-attendant, call recording, or a mobile app. All of these come standard with hosted VOIP. The one area to check is fax -- VOIP handles this via fax-to-email, which works well for most businesses.

Is VOIP call quality as good as Telstra?

On a decent internet connection (NBN 50+), yes. VOIP call quality on modern codecs is indistinguishable from a traditional landline. On slow or congested internet, you may notice a difference. Most VOIP providers recommend a minimum of 100 kbps per simultaneous call, which any NBN plan handles easily.

What about fax?

VOIP supports fax-to-email, which converts incoming faxes to PDF and delivers them to your inbox. Outgoing fax is also available. You no longer need a physical fax machine. This is actually an upgrade for most businesses -- faxes arrive as searchable PDFs and can be forwarded like any email.

Can I switch from Telstra without losing my number?

Yes. Number porting transfers your existing number to your new VOIP provider. It takes 5-10 business days and Telstra cannot refuse the port under Australian telecommunications regulations. Your number keeps working on the old system until the port completes, so there is no gap in service.
