Automatic Number Translation
Automatic Number Translation (ANT) can be used to modify the numbers dialed by users into a different number
string before dialing out the number.
ANT can be used to modify the dialed destination numbers to match the specific route number plan of the
destination networks or when the network requires adding or stripping off of the prefix of the destination number
strings.
ANT can be used for Speed Dialing. It is also the basis of the feature
, used from the Mobile
Port of SIMADO GFX11.
Automatic Number Translation makes use of a table in which two types of number strings are configured:
•
Dialed Number Strings:
These are numbers that need to be modified when dialed out from the system.
•
Substitute Number Strings:
These are numbers which the system should dial out in place of the dialed
number strings.
You can configure up to 6 Dialed number strings and their corresponding Substitute number strings in the ANT
table. The Dialed numbers and their corresponding Substitute numbers are stored in the ANT table at an Index,
from 1 to 6.
Whenever an outgoing call is made from the FXS Port, SIMADO GFX11 matches the dialed number with the
entries of this table using the best-match-found logic. If a match is found, SIMADO GFX11 will dial out the
Substitute number string configured for the dialed number string in the ANT table.
Let us understand this feature with the help of an example.
A user dials 952652631721 from the telephone connected to the FXS Port, out of habit. SIMADO GFX11 routes this
call through the Mobile Port to the desired destination. However, the GSM network does not understand the dialed
number string, because it expects the user to dial +912652631721. The call is rejected.
You can avoid this by configuring the Automatic Number Translation table with the prefix of the numbers that you
expect users to dial as Dialed number strings and the prefix expected by the GSM network in the Substitute
Number list. In this case,
•
95
, which is the prefix of the number 952652631721 is configured as the Dialed Number String.
•
+91
which is the prefix understood by the GSM Network is configured as the Substitute Number String.
With the ANT Table configured thus, whenever a number is dialed from the FXS Port, the system matches the
number string with the ANT Table. If a match is found, the system dials the Substitute Number string configured for
that number in the table.
The ANT Table you must configure for the above example, is as under:
Index
