Clipping occurs when words are cut up in a conversation and you only hear half of the word: For example, you hear “-osis” and are unsure if the doctor on the other end said “halitosis” or “trichinosis.”
Drops occur when an entire word is dropped which may affect the meaning of a sentence: For example, “The MRI showed that the (benign) brain tumor was below the cerebellum.” The dropped word, “benign,” substantially changes the meaning.
Clipping and drops in a VoIP conversation come from two potential sources:
Finding where and why packets were dropped can be challenging, as that they can be lost in many different locations, for a wide variety of reasons. Some of the primary reasons that packets are lost in a network include:
Out-of-order packets are packets that were successfully delivered to the destination device, but were not in serialized order. This can occur when there are multiple paths to the destination and incorrect load balancing is employed. Per-flow load balancing should be used for all redundant links and equal cost routing for layer-3 should not be used.
