Automatic Number Translation
SARVAM UCS offers connectivity to different networks—CO, GSM/UMTS/LTE, VoIP—each having a different
numbering plan. For example, the GSM/UMTS/LTE network requires area codes to be dialed for local numbers,
whereas CO requires dialing of area codes for long distance calls.
When SARVAM UCS 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 SARVAM UCS 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/LTE, 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 SARVAM UCS 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 (ANT) Table. You can configure
upto 32 entires in each ANT table.
The ANT Table consists of three columns, namely:
• Dialed Number String: This column contains the numbers you expect the users to dial.
• Strip Digits: 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.
You can configure the ANT table for each trunk separately.
Here is an example of how this table is to be configured and used:
Say, 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’.
• first 2 digits to be stripped off from all numbers beginning with 91 and ‘0’ to be added as a 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.
Thus, the entries you will need to make in the ANT table will be as follows:
Dialed Number String Strip Digits Add Prefix
XXXXXXXXXX 0 1
