NBN Phone systems costs will vary based on the number of handsets and channels required to connect them. The basic NBN Modem will come with 4 ports so that will give capacity for you of up to 4 handsets. If more than 4 handsets are required a Cisco POE (Power Over Ethernet) switch will need to be added to the system. Switches come in units with 8 and 24 Ethernet ports. As power is delivered over the POE switch ports via a Ethernet cable, Power Packs are not required for the Handsets.
So for an indicative calculator to price your NBN phone system hardware
Each System will need 1 X NBN Capable Modem at approx $200
Each Handset will be approx $250, so multiply the number of handsets required x $250
If more than 4 Handset are required you will need to add a switch in… 8 Port $500 or 24 Port $850
So when we add things together for example a 6 Handset NBN Phone System would be as follows …
Modem X 1 ($200)
6 x handsets ($1500)
1 X 8 Port Switch $500) = Total $2200 inc Gst.
A 4 Handset NBN Phone System would not need the 8 Port POE Switch so it would be…
Modem X 1 ($200)
4 X Handsets ($1000) = TOTAL $1200 Inc GST.
