This is calling re-INVITE, and can be turned on on asterisk. For other protocols there are similar features. I think your latency figures are a little bit exaggerated if you speak about the network latency. I am in Spain and my latency to China at my home ADSL is arround 80ms for mainland. 250ms to Tokio tough.
