I am wondering what the limitations of Voice over IP are in respect to Latency. I am looking at a high latency network (around 400ms RTT) due to utilisation and distance, and I am wondering what kind of effects this is going to have
You will find that your latency times will be unaccepable for voice traffic. Typically, the "magic number" you want to shoot for is roughly 125mS of latency or better. Although....cisco claims that the last space shuttle that went up used softphone via satellites and it worked fine....I wonder what fine really means?
