Delivering voice over the network requires jitter to be less than 50ms in most cases. if VoIP packets exceed 50ms then quality issues will occur. This will take the form of poor quality speech sounding like talking under water or completely lost words or sentences. Learn More

Delivering voice over the network requires packets to travel in both directions. The connection test indicates there is a large inconsistency in the jitter in one of the directions. if VoIP packets have a high variance in jitter from between upstream and downstream then quality issues will occur. This will take the form of poor quality conversation caused by timing delays in the voice at each end as well as poor quality audio. Learn More

Delivering quality voice over the network requires all packets sent to arrive in a timely fashion. If packets are delivered late or even early for any reason then this will cause the speech quality to decline as late packets that exceed the buffer time limit have to be discarded. The extent of the quality loss will depend on how many packets are discarded and the distribution of that loss over the time line of the test. Learn More

Delivering quality voice over the network requires all packets sent to arrive in a timely fashion. If packets are delivered out of order for any reason then this can cause the speech quality to decline. For example if a packet for the beginning of a sentence arrives in the middle sentence then it is likely that the packet will be too late for acceptable usage and will be discarded. The extent of the quality loss will depend on how many packets are out of order, early or late, and as a results become unusable in the context of uniform speech. Learn More
