Concept 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 dierent network
policy than the media packets for which a connection is made. In this case, congure the signaling application.

3 Guest Voice Specify this application type for a separate limited voice service
for guest users with their own IP telephony handsets and other
appliances supporting interactive voice services.
4 Guest Voice Signaling Specify this application type only if guest voice control packets
