user
The Cisco IPICS user may set up personal login information, download the PMC
application, customize the PMC skin, and specify communication preferences
that are used to configure audio devices. By using a predefined user ID and
profile, the user can participate in PTT channels and VTGs by using the PMC or
a supported Cisco IP Phone model. Users may have one or more Cisco IPICS
roles, such as system administrator, operator or dispatcher.
unicast
Specifies point-to-point transmission, or a message sent to a single network
destination.
V
VAD
Voice Activity Detection. When VAD is enabled on a voice port or on a dial peer,
only audible speech is transmitted over the network. When VAD is enabled on
Cisco IPICS, the PMC only sends voice traffic when it detects your voice.
virtual channel
A virtual channel is similar to a channel but a radio system may not be attached.
By creating a virtual channel, participants who do not use physical handheld
radios to call into a VTG become enabled by using the PMC application or
Cisco IP Phone 7960 or Cisco IP Phone 7970.
voice
interoperability
Voice interoperability enables disparate equipment and networks to successfully
communicate with each other.
VoIP
Voice over Internet Protocol. By digitalizing and packetizing voice streams,
VoIP provides the capability to carry voice calls over an IP network with
POTS-like functionality, reliability, and voice quality.
volume indicator
The volume indicator on the PMC that shows the current volume level on the
channel in a graphical format.
volume up/down
buttons
The buttons on the PMC that let you control the volume level.
