# Voip Quality

Several factors can attribute to the quality of a Voip call. Most
problems with Voip quality can be narrowed down to packet loss, jitter,
wrong configurations, high latency and network attacks.

## Packet Loss

Packet loss happens when a defined number of packets don\'t all reach
their destination. Most commonly, this can happen from faulty network
hardware and wiring. Network saturation can be a culprit also on the WAN
and LAN of a network.

0% packet loss is recommended.

## Jitter

Packets that don\'t arrive in the intended order or proper time will
result in jitter. This will sound like robotic voice or missing audio
that sounds choppy. Much like a cell phone conversation with poor
reception.

3 ms in jitter or less is recommended.

## Latency

Too high of latency will result in conversational timing issues. This
sounds like two people talking at the same time.

150 ms or less is recommended.

## Wrong Configurations

-   Quality Of Service QOS when implimented correctly on a network
    device can help a network provide great Voip quality.
-   ISP provisions your cable modem the wrong speed profile.

## Network Attacks

We are in the age of the internet wild wild west. Network attacks
depending on size can bring a voip call quality sounding like packet
loss, jitter and latency kind of calls.
