- 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.
