5. Enter the phone number you are looking for under Search for. You
can enter up to four numbers divided by commas (,). The following
wildcards for digits are allowed: + for exactly one digit or no digit, *
for any number of digits, ? for exactly one digit.
You can enter more than one asterisk (*) within a calling number (for
example *123*678). One asterisk is always automatically entered at
the end of the number. Thus, numbers that are too long can be found. If
calling numbers are initiated by + or * the filter mode starts working
only after the number is confirmed by an ACM (Address complete) or
an ANM (Answer message). That means that all messages are
transmitted until then, because they belong to a call with a correspond-
ing number.
If you are looking for numbers with prefixes (for example international
area code) at one and the same time, you will get more specific outputs
by entering the exact numbers (for example 4930386,30386) than
by entering numbers initiated by “+” or “*” (++30386,*30386).
6. Specify whether the phone number designates a Calling Party or
a Called Party in the Type of number field.
7. Specify whether it is a National, an International or a
Subscriber number without a national/international area code in
the Nature of Address field. Select don’t care to include
all numbers.
8. For protocols you can specify Cause Values as additional search
criteria. The Calltrace application then searches for calls that contain
the desired number and one of the selected cause values (reason for the
end of call).
9. Specify the number of calls to be traced in the Trace mode field:
one (Single) or any number of matching phone numbers (Multi-
ple).
If you activate the filter mode, only the calltrace messages will be
displayed. Other messages will be suppressed. The asterisk (*) at the
beginning leads to more detailed infomation.
