Get a RecommendationMost Australian VOIP providers charge between $22 and $42 per user per month for a hosted plan. Basic plans start around $22/seat and include standard call features, while premium plans with call recording, advanced IVR, and CRM integrations run $40-50/seat. On top of the per-seat fee, factor in hardware costs ($150-450 per handset), any 1300/1800 number fees ($10/month), and one-off setup and porting fees. For a typical 10-person office on a mid-tier plan, expect $300-400/month ongoing plus $2,000-3,000 in first-year setup and hardware costs.
For most Australian businesses, VOIP is cheaper than traditional landline systems, especially once you factor in line rental, call charges, and hardware maintenance. A traditional PABX system with Telstra ISDN lines typically costs $50-80 per line per month plus call charges. VOIP plans bundle calls (often unlimited local and national) into the per-seat price. The savings are most significant for businesses with 5 or more staff, multiple locations, or high call volumes. The main exception is very small businesses (1-2 people) with low call volumes, where a simple mobile plan may be cheaper than VOIP.
Yes. The most common hidden costs include: number porting fees ($15-25 per number), hardware that needs replacing every 5-7 years, network switch upgrades if your existing switches do not support Power over Ethernet (PoE), internet bandwidth upgrades for call quality ($20-50/month extra), and training time for staff (2-4 hours per person). Some providers also charge extra for call recording, additional voicemail boxes, or API integrations. Always ask for a fully itemised quote including setup, porting, and any per-feature add-ons before signing.
A standard Australian VOIP plan typically includes: unlimited local and national calls, a softphone app for desktop and mobile, voicemail with email forwarding, basic call routing and ring groups, an online management portal, and standard support. Features like call recording, advanced IVR menus, CRM integration, call analytics, and 1300/1800 number hosting are usually only included on mid-tier or premium plans, or charged as add-ons. Hardware (desk phones, headsets, conference phones) is almost always a separate cost.
Most Australian VOIP providers include unlimited local and national calls in their standard monthly plans. This is one of the key cost advantages over traditional phone systems, which often charge per-call or per-minute for national calls. However, calls to mobiles may be metered on cheaper plans, and international calls are almost always charged separately or available as an add-on bundle. Calls to 13/1300 numbers are typically included, but calls to 1800 numbers from your hosted system may incur per-minute charges depending on your provider and plan.
