Figure 24: Example of Digit Manipulation Settings
The following examples illustrate how digit manipulation works in different queries. The queries
are considered to be done from 463155xxxx (local exchange), see also figure above.
• Example 1: The query is within the same local exchange. Queried number: 551234 Digit ma-
nipulation identifies 55 as the local exchange prefix and strips 55 from the number. Resulting
number: 1234
• Example 2: The query is within the same city (area code), but outside the local exchange.
Queried number: 031612500 Digit manipulation identifies 0 as National Prefix and 31 as Na-
tional Destination Code, strips 031 from the number and adds 00 for external line. Resulting
number: 00612500
• Example 3: The query is within the same country, but not in the same city. Queried number:
035158115 Digit manipulation identifies 0 as National Prefix and 35 as National Destination
Code and adds 00 for external line. Resulting number: 00035158115
• Example 4: The query is within another country. Queried number: +4781530555 Digit manipu-
lation identifies “+47” as an international call, skips the “+”, and adds 00 for external line prefix
and 00 for international prefix. Resulting number: 00004781530555
• Example 5: Size of internal number. Queried number: 1234 Digit manipulation identifies that
the number of digits in the telephone number is equal to the number of digits entered as
“maximum size of internal phone numbers”. Resulting number: 1234
