Automatic Number Translation - Matrix ETERNITY NE System Manual

Automatic Number Translation

What's this?
ETERNITY NE offers connectivity to different networks—CO, GSM/UMTS, VoIP—each having a different
numbering plan. For example, the GSM/UMTS network requires area codes to be dialed also for local numbers,
whereas CO requires dialing of area codes for long distance calls.
When ETERNITY NE is connected to more than one network, outgoing calls may be routed through any of these
networks, depending on the outgoing call routing configured in the system. However, as extension users do not
know through which telecom network their calls will be routed, they cannot be expected to dial numbers according
to the numbering plan of the destination networks.
The feature, Automatic Number Translation of ETERNITY NE takes care of this. It modifies the dialed numbers or
part thereof to match with the specific route numbering plan understood by the destination network (CO, GSM/
UMTS VoIP). This includes adding or stripping of country codes and area codes.
For example, when an extension user dials a local landline number, Automatic Number Translation can be
configured such that the ETERNITY prefixes the number with the appropriate country-area code when it routes the
call through the GSM/UMTS network.
How it works
Automatic Number Translation makes use of the Automatic Number Translation Table which comprises:
• Dialed Number Strings - the numbers dialed by the extension users
• Substitute Number Strings - the corresponding numbers for the Dialed Numbers that the system will dial
out as the destination numbers instead of the dialed numbers.
The Dialed and Substitute Number strings must be configured, and the Table must be applied to the trunk ports,
through which calls are routed to the destination networks. The trunk ports may be CO Trunks, Mobile, SIP,
depending on system configuration.
You can configure different 8 Automatic Number Translation Tables; each table accommodates 32 Dialed Number
strings and their corresponding Substitute number strings. A trunk port can be assigned only 1 Table.
For example:
• Automatic Number Translation (ANT) Table-1 has '95' stored as Dialed Number string in Index-1 and '91'
as the corresponding Substitute Number string at Index-1.
• The ANT Table-1 is assigned to Mobile port 1.
• When extension user A dials '952652630555', the system
• detects the outgoing trunks assigned to Extension A.
• checks if Automatic Number Translation feature is enabled on the outgoing trunks selected for
Extension A.
