Glossary
Terminology
STUN
Simple Transversal of UDP over NATs - used to determine the public IP
address of an Internet connection. To do this, a STUN request is sent to a
STUN server, which then shares its own IP address allocated by the VoIP
provider with the Internet connection.
Subnet mask
The value of the subnet mask, as with IP addresses, is often given in
decimal form (for example, 255.255.255.0 for IPv4 addresses).
Switch
Active network distributor that distributes data packages to a destination
defined by an IP address among the different segments of a network.
Syslog Server
Records protocols with control and management information about the
PBX. This information helps to identify errors and, where possible, their
causes.
