NEC channel partner Telelink Business Systems has claimed technology advances have cut out two thirds of what it used to cost to deploy a new phone system.
Its managing director Alan McKibbin said it had "recently completed a head-to-head comparison of hardware costs for phone systems sold during the past decade with current systems."
It did not specify the hardware it used in its calculations.
But it claimed a small business phone system with four lines and 16 handsets would now cost $4847 instead of $14,110 in 1998.
An enterprise phone system with 30 lines and 160 extensions had dropped to $21,825 from $66,700 in 2003 "for a similarly configured system", McKibbin said.
McKibbin said Telelink's most popular phone system was the NEC SV8000 IP Phone series. The company is based in Adelaide.
