+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.

+Voip Quality Testing Websites

+
+
+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.
