Now and again I look seriously at the viability of using voip rather than POTS.

I currently use a combination of BT, 18185.co.uk, and Talk Talk (Routed with
an Orchid device).

A number of those calls are free. Out of the chargeable ones, the total cost
over a one month period was £3:78.

I've calculated what the cost would have been (I think) using Sipgate, and
their standard call charges.

It comes out at £ 6.03. No contest, and I've not included the outlay for the
voip hardware, or included the voip cost of the free calls I currently get via
TalkTalk, these would add another fiver.

The calls are a mixture of 60% UK landline, 30% UK mobile, 10%
0870/0845/international.

Under what circumstances is voip a better deal, or have I got my sums very
wrong ?
