Closed User Groups (CUGs)
Closed User Groups (CUGs) are groups to and from which
access is restricted.
Members of a CUG can usually communicate with each other,
but not always—it depends upon the way the network
provider has set up the CUG. Depending on the protocol and
the way the CUG is set up, the members may also be able to
make calls to users outside their group, but they cannot
normally receive calls from the outside.
To check the operation of CUGs on a link, you can assign a
CUG number to your aurora

, then try to make calls to
devices within and outside the CUG.
