H.323 is a set of standards for transmitting voice calls over an IP network. A 
number of Windows-based applications allow telephone calls to be made from one 
H.323 compliant PC, with a microphone and speakers or headset, over the IP 
network to another H.323 compliant PC. The DEFINITY IP Trunk application 
supports H.323 telephone calls and Microsoft NetMeeting. This means that 
NetMeeting can make a call to a DEFINITY ECS with the DEFINITY IP Trunk 
application. That switch may route the call off-premise, depending on how the 
DEFINITY ECS application is configured. 

Refer to ‘‘Configuring Microsoft NetMeeting™’’ on page 384 for instructions.
