Configuring
Number Translation
Patterns
(DIRECTORY)
To successfully communicate with other voice networks, the VCX system
translates numbers based on source and destination calling patterns.
For example, if an end user dials number 456789 and the number
translation is configured so that the source pattern equals *and the
destination pattern equals 456*, the result pattern is *@3com.com. In
this example, the “*” is 789 because the user dialed 456789 and the
destination pattern is 456*. 789 is used in place of the * in the result
pattern, and the translation is 789@3com.com. 456789, the original
phone number, gets translated as 789@3com.com and is processed
accordingly.
You can use the VCX Administrator application to manage number
translation on either the USERS interface or the DIRECTORY interface.
This section describes how to configure number translation through the
DIRECTORY interface. Number translations configured in one interface do
not appear in the other interface.
Understanding
Translation
Algorithms
This section describes how pattern matching and translation strings are
used. The outbound destination number is translated using the match
pattern ID and translation string. The match string is a regular expression
that matches the outbound destination number. The translation string
determines how the destination number is translated. The translation
string is specified with a semi-regular expression format. A translation
string with an asterisk (*) means perform no translation just use the full
destination number string that matched in the match string. A translation
string with pre-pended characters has those characters pre-pended to the
translated destination number.
