Are You VoIP Ready? – What Stable Connections Look Like

postheadericon Are You VoIP Ready? – What Stable Connections Look Like

Figure 5 is a good example of a connection that should work for your VoIP application. In this screen shot, showing a 24 hour segment, you can see that there are only a total of 5 samples that go into the yellow area. The vast majority are in the lower middle of the green band with the average latency at 73ms and jitter of 4ms. As such, I would tell the customer that this circuit meets my criteria of VoIP readiness. The only thing I do not know for sure is how much bandwidth they have. Sometimes the customer will know and other times they will think  they know. If it is a T-1 connection, then you can be fairly certain that you are getting 1.54M up AND down and base your voice session calculations off of that. If it is a DSL or cable connection, you will most likely experience swings in latency as usage (voice and data) goes up.
