I will be looking for a good solution as well. Always used BuzzMore, which wasn't too bad, although the line quality wasn't that hot, but they have closed down, "due to Telkom dropping their international call rates." Meaning? IMO Telkom bought them out, and closed them down, because all of a sudden my phone bill is doubled!
Therefore, Skype became a real alternative! Am already using it to those friends that have a computer and a :sob: 2Mbit link... but still need something for the rest of the family!
