LTGSM User Manual C11 Confidential
Normal External
When ticked, authentication will be required upon the handset roaming from an ‘external’ cell
(i.e. macro network), to a PMX cell.
Normal Internal
If ticked, authentication will be required when a handset roams from one PMX cell to another.
Attach
When this option is ticked, PMX will attempt to authenticate the SIM when the extension
attempts to register back on the network.
Calls
When selected, this option sets PMX to authenticate the SIM whenever the extension
attempts to make a call.
Periodic
Each mobile handset will attempt to re-register regular intervals – the norm being 90 minutes.
The frequency is set in the IP Access configuration. This setting determines whether or not
PMX attempts to authenticate the SIM with each re-registration. If un-ticked, the mobile will be
allowed to re-register without authenticating again.
Ciphering
Allows the radio traffic between handsets and cells to be scrambled. The encryption
algorithms are set on each cell in the IP Access configuration.
For further information about authentication, please refer to the authentication settings for
extensions.
Diverts Tab
There may be a requirement to forward / divert calls to other destinations under certain
conditions. For example, you may wish to divert calls to a voicemail system or a switchboard
if an extension is busy. These diverts may either be set at tenancy level, i.e. all extensions
within the tenancy will follow the same diverts (unless overridden by an extension-specific
divert) or on individual extensions. The diverts tab within the ‘Tenancy Settings’ will apply the
rules for all extensions within the tenancy.
