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 within +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
