5.5.1 Basics of Voice over IP (VoIP)

The VoIP service functionality enables a radio to perform voice communication with an ex-
ternal VoIP user over an IP network. The external VoIP user is an IP-capable device such as
a VoIP telephone or the R&S GB4000V.
Remote operation is a typical use case of the VoIP service, where besides the voice over IP,
the remote control of the radio is also performed via IP.
The Figure 5.28 shows an IP-based remote operation application.

The VoIP service can be used for a voice communication between an external VoIP user and
a radio network. For this purpose, one radio in the radio network acts as VoIP gateway. The
VoIP gateway radio is connected via Ethernet to an IP network and handles calls originated
from or coming towards the radio network. Any radio in the network can act in the role of VoIP
gateway. This role is configured via R&S RNMS3000.
