VoDSL – Read Before Signing

I will start out by saying that it is my personal view after seeing hundreds of VoDSL installations over the last 5 years that VoDSL really only benefits the service provider, not the end user. There are marginal savings to be had through the low cost line rentals that are offered but the reduced cost comes with reduced reliability. Some would argue this but there is no denying that having all of your phone lines on a single pair of wires is more likely to fail than having the lines spread out on their own wires.

VoDSL is not new, it has simply become popular in the last 3-4 years. VoDSL exists purely as a work around for telephone companies (other than Telstra) to avoid paying for the rental of the copper wire between the exchange and your premises. As Telstra owns these cables, all other service providers must pay a fixed monthly fee for each phone line. VoDSL is essentially an internet connection which works over 1 copper line and is able to deliver up to 8 analogue phone lines minimising the cost to the service provider.

VoDSL Pros

  • Reduced line rental costs
  • Internet sometimes free or very cheap
  • Local calls tend to be cheaper


VoDSL Cons

  • Installation usually requires contract of 24 months or more
  • Reduced reliability
  • Potential to have all phone lines and internet down at the same time
  • Internet download speeds are very slow by todays standards
  • Once off the Telstra network, it becomes difficult to come back.
