Prevent Choppiness and Packet Loss

A choppy call usually indicates packet loss. When audio drops, clips or cuts out, it means data files have been lost between points A and B.

Primarily, there are two types of packet loss: random and burst. Random packet loss results in missing syllables—or choppiness. Burst packet loss translates into extended periods of silence. Both affect quality, but the latter is much worse.

Solutions

Packet loss occurs for many reasons:

  • Packet collision
  • Spiked bandwidth usage
  • Strict jitter buffer
  • Poor audio codecs

A 5% packet loss rate is acceptable; anything more becomes noticeable. Audio codecs compress and decompress files, contributing naturally to this loss. The more efficient it does so, the less chance of further data loss en route.

Prioritizing network data can improve choppiness and dropped calls. This involves configuring a router with QoS and allocating data to voice devices (i.e. IP phone). Remember to reboot network devices to activate changes to the settings. Plug VoIP devices into other network components, too, for best results (i.e. Ethernet).
