Reference Guide
NOTE: As shown in the following table, signaling is a series of control packets that are exchanged 
between an endpoint device and a network connectivity device to establish and maintain a 
connection. These signal packets might require a different network policy than the media packets 
for which a connection is made. In this case, configure the signaling application.
