WARNING
The software contained in the TRS/Barring feature to allow user access to the network must be
upgraded to recognise newly established network area codes and exchange codes as they are
placed into service.
Failure to upgrade the on-premise PBXs or peripheral equipment to recognise the new codes as
they are established will restrict the customer and users of the PBX from gaining access to the
network and to these codes.
