Proxy/proxy server
Computer program that controls the exchange of data between Client and Server in
computer networks. If the phone sends a query to the VoIP server, the proxy acts as a server
towards the phone and as a client towards the server. A proxy is addressed via
IP address /
Domain name and Port .
Public IP address
The public IP address is the address for a network component on the Internet. It is assigned
by the Internet service provider. Devices that act as a link from a local network to the Internet
(gateway, router) have a public and a local IP address.
See also: IP address , NAT .
Q
Quality of Service (QoS)
Describes the quality of service in communication networks. Differentiations are made
between various quality of service classes.
QoS influences the flow of data packets on the Internet e.g., by prioritising data packets,
reserving bandwidth and optimising data packets.
In VoIP networks, QoS influences the voice quality. If the whole infrastructure (router,
network server etc.) has QoS, the voice quality is better, i.e., fewer delays, less echoing, less
crackling.
R
Registrar
The registrar manages the current IP addresses of the Network subscriber . When you
register with your VoIP provider, your current IP address is saved on the registrar. This means
you can also be reached when on the move.
RFP
Radio Fixed Part
Base stations in a multicell DECT network.
RFPI
Radio Fixed Part Identity
ID for a base station in a multicell DECT network. It includes the number (RPN) and an ID for
the DECT Manager. A handset uses it to recognise the base stations it is connected to and the
DECT network to which it belongs.
Ringback when the call is not answered
= CCNR (Completion of calls on no reply). If a party does not reply when called, a caller can
arrange an automatic ringback. As soon as the destination phone has completed a call and
is free again, the caller is called back. This feature must be supported by the exchange. The
ringback request is automatically cancelled after about two hours (depending on the
network provider).
Ringback when the number is busy
= CCBS (Completion of calls to busy subscriber). If a caller hears the busy tone, he or she can
activate the ringback function. As soon as the connection is free, the caller is called back. As
soon as the caller lifts the earpiece, the connection is made automatically.
Roaming
Possibility for a subscriber with a DECT handset to accept or make calls in all cells of a DECT
network.
