Viewing Call Progress
The Call Progress dialog box is a read-only screen that displays the status of a call in
progress. This dialog box is accessed from the MVP120 Setup menu by clicking the Call
Progress button.
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 MVP120 to
recover many of the lost packets.
The Jitter value (measured in milliseconds) indicates the mean deviation of the difference in
packet spacing at the receiver compared to the sender for a pair of packets.
