VoIP Communications Providers
The following solutions typically cost pennies per minute for audio calls to/from/within US/Canada/UK and similar destinations. However, your mileage may vary (calls terminating at mobile phones in particular can be a lot dearer), so always read the fine print before you buy. Caveat Emptor, and all that. :-)
