The ratio of Packets Lost versus Packets Received provides a general indication of the integrity of
the Internet connection. To reduce the frequency of lost packets, select a low-bit-rate coder, such as,
G.723 or Netcoder. In addition, enabling the Forward Error Correction option on the Voice/Fax tab on
the Channel Setup dialog box will enable the MVP110 to recover many of the lost packets.
The Jitter value (measured in milliseconds) indicates the mean deviation of the difference in packet
