SUMMARY: [asterisk-biz] Does VoIP Really Work for Serious Business?

Depends on the availability of a jitter buffer.

Jitter will become added delay when a jitter buffer is used, and the 
jitter is not bigger than the max size of the jitter buffer.

The less delay the more people will like it. (300ms is about the maximum 
you can go).

If no jb is available, some packets will be dropped because they are out 
of order, and that will result in choppy audio.

So, jitter becomes an issue if it makes the delay grow too big to be 
acceptable or if it too much for the jitter buffer to reorder, or if 
there is no jitter buffer
