Automatic Number Translation (Ant) - Matrix Telecom SARVAM UMG System Manual

Automatic Number Translation (ANT)

Automatic Number Translation (ANT) is used to modify the number string—entire number or part thereof—into the
desired number string as per your requirement. ANT is useful when you need to modify the Called/Calling number,
before the system routes the call further.
For example, in India the PSTN requires you to dial the prefix 00 for calling international numbers, whereas the
ITSP you have subscribed the SIP Trunk with, restricts the dialing of the prefix 00. If you dial this prefix, your call
will be rejected by the ITSP. The ANT Table will enable you to modify the Number string as per your requirement so
that the calls routed through the SIP Trunk are not rejected.
The Automatic Number Translation feature can be applied on all the FXS Ports, FXO Ports, BRI Ports, SIP Trunks,
Mobile Ports and T1E1 Ports.
Automatic Number Translation makes use of Automatic Number Translation Table. The ANT Table consists of
three columns:
• Number: In this column, enter the numbers that you want the system to modify.
• Strip Digit: In this column, enter the number of digit(s) to be stripped off by the system from the Called/
Calling number string. If you do not want any digits to be stripped, enter '0'.
• Add Prefix: In this column, enter the digit(s) which are to be added as prefix to the Called/ Calling number
string by the system before routing it further.
To apply this feature on the desired port,
• on a piece of paper make a table, in the first column note down the numbers that needs to be modified. In
the second column enter the number of digits you want the system to strip off (if required), and in the third
column, enter the number you want the system to add as prefix (if required).
• configure the Automatic Number Translation Table. You can configure upto 8 different ANT Tables.
• enable Automatic Number Translation (ANT) for Called Number and/or Automatic Number
Translation (ANT) for Calling Number on the respective ports/trunks, on which you want to apply this
feature.
• assign the Automatic Number Translation Table you configured.
• configure the Pause Timer, if applicable.
