Newbie questions re calling abroad

[#1]

Hi,
We usually make one or two calls to Austrlia each week. Apart from VOIP, what's the cheapest way for us to do this - does anyone know a good callrouting system we could use?
I thought about using JustCall (1p/min via 0845) but what's the Plusnet rate for 0845 calls?
TIA.

Welcome to the forum,
Plusnet's home phone tariff can be found here...http://www.plus.net/residential/tariffs/homephone.html

An account with "call18866.co.uk" may be your cheapest option, 2p per minute from landlines + 5p connection charge.
If you use Skype Credit it is 1.6p per minute including Vat., but you have to pay £11.50 up front.

You could try the Money Saving Expert Call Checker here that lists call rates for lots of providers, by country.
