Hi Madman88,
YaClick is not a bad product, the only issue with voice is the latency, the calls sound like you are a million miles away, remember the latency from the sat to the bird is 300ms, so you need to go from the sat to the bird then back to the teleport station (600ms) and then back to South Africa, you can add another 200 ms to this, so you are looking at around 800ms. For Internet is not bad at all. Just watch out for Voxtelecoms contracts they are draconian !
