Glossary
Terminology and Functions
C
CNG (Comfort Noise Generation) creates an artificially-generated noise in the VoIP end device
that fills the speech pauses during a telephone call, thereby conveying the impression of an
existing connection to the local subscribers. Without CNG, there is an impression that the call
has been interrupted because nothing can be heard.
CNG supports codecs G.711 and G.722.
Codec
A codec is a method that encodes (digitizes) analogue voice data for transmission and again
decodes again, meaning converts into back into voice. There are various codecs that feature
different voice data compression rates thereby require different band widths for data trans-
mission. The equality of VoIP calls is dependent on the codec used.
Conference Calls
During a conference call, you are talking with two subscribers simultaneously.
Configuration Manager
The configuration manager lets you easily configure the PBX on your computer. It is reachable
over the integrated Web server on the PBX. The required PC is connected either directly to a
Ethernet port on the PBX or it must be on the same network.
Configuration Switchover
If multiple configurations have been saved, for example, for day, night, etc., switching over from
one configuration to another can be carried out manually and/or in a time controlled manner.
Cross-Site Scripting (XSS)
In the case of Cross-Site Scripting (XSS), a security hole in web applications can be used to
access the data of another user.
