Matrix PRASAR UCS - Automatic Number Translation

Matrix PRASAR UCS System Manual 589
Automatic Number Translation
What's this?
PRASAR UCS offers connectivity to VoIP networks and these may have different plan. For example, the ITSP
requires area codes to be dialed also for local numbers.
When PRASAR UCS is connected with such VoIP networks, outgoing calls need to be routed through these trunks.
However, when extension users dial local number they cannot be expected to dial numbers with area codes.
The Automatic Number Translation feature of PRASAR UCS takes care of this. It modifies/manipulates dialed
numbers or part thereof to match with specific route numbering plan understood by the VoIP network. This includes
adding or stripping off of country codes and area codes.
For example, when an extension user dials a local landline number, if Automatic Number Translation is so
programmed, the PRASAR UCS will prefix the number with the appropriate country-area code before routing the
call through the VoIP network.
How it works
Automatic Number Translation makes use of the Automatic Number Translation (ANT) Table. The ANT Table
consists of three columns:
• Dialed Number: This column contains the numbers you expect the users to dial.
• Strip Digit: This column contains the number of digit(s) to be stripped off by the system from the Dialed
Number string before dialing it out.
• Add Prefix: This column contains the digit(s) which are to be added as prefix to the Dialed Number string
by the system before dialing it out.
This table is applied on the desired trunk, through which outgoing calls are made.
Upto 8 different ANT tables can be configured and each table can accommodate upto 32 strings.
Here is an example of how this table is to be configured and used:
You want
• All 10-digit numbers to be dialed out after adding the prefix ‘1’.
• All 7-digit numbers, starting with 2 to be dialed out after adding the prefix ‘1315’.
• All numbers beginning with 91 to be stripped off the first 2 digits and ‘0’ to be added as prefix.
When you do not want to specify any numeric digits in the numbers to be modified, use the character X. This
character represents any numeric digit from 0 to 9. For example, a 10-digit number (having the numeric digits from
0 to 9) can be represented using this character as XXXXXXXXXX.
