Field Description
Call Analysis Delay
Defines the amount of time, in centiseconds, that the
messaging system will pause before attempting to detect a
signal pattern on the phone line.
Ring to begin on
Specifies the number of signal patterns the messaging
system will ignore before attempting to identify the incoming
signal.
Debounce silence
Specifies the minimum length of silence, in centiseconds,
that must be detected before the system observes a
high-to-low change of state.
Voice
Specifies the minimum length of nonsilence that must be
detected before the system observes a low-to-high change
of state.
Leading edge detect
Select the enable leading edge detect.
Tolerance above 1st low
%
Below 1st low %
Tolerance above 2nd
low %
Below 2nd low %
Tolerance above 1st
high %
Below 1st high %
The three sets of tolerance levels correspond to the
variations in two low states and one high state of a signal
pattern definition. Expressed as a percentage of the length of
the high or low state, the tolerance level defines the margin
of error for the signal.
For example, if Tolerance above were set to 5 and Below
set to 6, any signal between 94% and 105% would be
considered a valid signal.
Very small tolerance levels make call progress quick, but
some signals might be incorrectly read.
Large tolerance levels, the messaging system responds to
signals that are not as accurate, but slows call progress.
Very large tolerance levels might allow a human voice to be
interpreted as a valid signal.
Max short in dbl ring
The maximum length, in centiseconds, that the messaging
system allows for the period of silence between two rings
that make up a double ring on phone systems that use a
double ring.
Min long low
The minimum length, in centiseconds, that the messaging
system allows for the long period of silence between two
double rings on phone systems that use a double ring.
Max time busy
The maximum length, in centiseconds, that the messaging
system allows for each of the low segments and the high
segments of a busy signal.
Max time busy 1st low
The maximum length, in centiseconds, that the messaging
system allows for the first low segment of a busy signal.
Max time busy 2nd low
The maximum length, in centiseconds, that the messaging
system allows for the second low segment of a busy signal.
Busy states over rings
The number of busy patterns more than the number of
ringback patterns the messaging system must detect before
determining that the phone it is calling is busy.
Size of long high
The length, in centiseconds, used to determine if the phone
system is sending a double or single ringback signal.
Max sil. long
If a nonsilence signal is not heard within this time, the
messaging system assumes the ringback signal has been
interrupted and continues call progress.
Short
If the length of the first nonsilent period is less than the size
of long high, a double ringback signal is assumed and the
messaging system only listens for the next period of
nonsilence up to the length specified in Short. Lengths
specify centiseconds.
