Set of rules for filtering out SIP lines

You can enter rules that determine whether lines should be filtered out during readout or not. If "no detection of SIP lines" is selected, all read-in lines will be included in the line management. If "Rules for recognizing SIP lines" is selected, a set of rules is applied when the lines are read in, which determines whether a line should be included in the line management or not. This set of rules consists of individual entries created by the user.

Each entry has one of four possible entry types and a corresponding string to search for. The following entries for a rule are possible:

String in name
When lines are read in, only those lines are included in the line management whose line name does not contain the character string entered in the "Search for:" column.
Example:

String in the phone number
When lines are read in, only those lines are included in the line management whose phone number does not contain the string entered in the "Search for:" column.
Example:

Regular expression in name
The string in the "Search for:" column must be a regular expression. When the lines are read in, only the lines for which the search using the regular expression in the line name was unsuccessful are included in the line management.
Example:

Regular expression in the call number
The string in the "Search for:" column must be a regular expression. When lines are read in, only those lines are included in the line management for which the search using the regular expression in the phone number was unsuccessful.
Example:

String	Description
^	The beginning of the phone number or name. The regular expression "^0" or the regular expression "^Max" finds the search character '0' or the search string "Max" only at the beginning of the phone number or name.
$	The dollar sign ($) indicates the end of the phone number or name. The regular expression "152$" finds the string "152" only at the end of the phone number or name.
\|	The (\|) character allows both characters between which it is located. The expression "8\|9" allows '8' or '9'.
.	The dot (.) allows any character (or any digit).
*	The asterisk (*) indicates that the character to its left must be present 0 times or more.
+	The Plus sign (+) is similar to the asterisk, only the character to the left must be present at least once.
?	The question mark (?) indicates that the character to the left must be present 0 or 1 times.
[]	The square brackets ([ and ]) signal a set of characters that are allowed at this point.

Check:
You can directly check your set of rules in the "Rules for detecting SIP lines" dialog box. Enter a character string in the Search Text field that you want to test with the set of rules. In the "Detected as SIP line:" field, you can see whether a rule for filtering was successfully applied to the search text.
