Viewing Call Progress
The Call Progress dialog box displays the status of a call in progress. This dialog box is accessed
from the MultiVOIP Setup menu by clicking on 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 Forward Error Correction option in the Channel Setup dialog
box under the Voice/Fax tab will enable the MultiVOIP to recover many of the lost packets.
The Jitter (ms) value indicates the mean deviation of the difference in packet spacing at the receiver
compared to the sender for a pair of packets.
