Ensuring Optimum Sound Quality 
Excellent sound quality is an essential element of MeetingPlace conferences. 
Improving the sound quality depends on understanding and adjusting for 
several “real-world” factors: 
 
Network trunk operating conditions (audio levels, background noise, 
echo, and so forth) are inconsistent throughout the world. 
 
Varying audio levels differ among speakers in a conference. 
 
Large meetings often have rapidly changing speakers. 
 
Room operating conditions vary (offices, conference rooms, 
auditoriums, and so forth). 
MeetingPlace has been designed to take all of these factors into account, and 
its Digital Signal Processing algorithms provide the best overall sound 
quality for a wide range of operating conditions. 
Techniques for Improving Sound Quality 
Some MeetingPlace installations have encountered and resolved sound 
problems caused by a variety of conditions, ranging from trunk type 
configurations to the acoustics in conference rooms. The problems and their 
resolution are discussed below. 
Line Termination Types 
The MeetingPlace system can work with a variety of trunk types and 
configurations, but minimizing the equipment between the network and the 
system is ideal.
