THE NETWORK OFFERINGCALL SERVER : PRIVATE NETWORKS

BREAK-IN / BREAK-OUT
Break-in and break-out services make it possible to carry out inter-establishment communications from
a private network; this is realized with the use of lines leased between 2 or more PABXs belonging to
this private network.
Break-in
This service corresponds to the transit of incoming calls from the public network to a private network
via leased lines; thus, an external correspondent can join a private network user who is not connected
to the same system as the line on which the call is routed.
Break-in can be implemented in 2 ways:
- automatically by DDI numbers
- manually by the operator (joining by transfer)
For the caller, it is also possible to set up a simple directory (a single group of numbers to call all users
from one or several sites).
