Connect Time
There are three connect time statistics that you can bill for: user connect time, caller connect
time, and call placement connect time. All these statistics are accumulated in the same way, but
you can have a different set of rates for each port (line) group in the server. These statistics
measure off-hook to on-hook phone line usage.
• User connect time is the time used by the mailbox owner to pick up messages and/or to
make messages for other mailbox owners. The rates you set for user connect time apply to
all calls through the specified port (line) group.
• Caller connect time is the time charged when outside callers leave messages in a mailbox
or listen to the greeting of a Greeting-Only mailbox. The rates you set for caller connect time
apply to all calls through the specified port (line) group.
• Call placement connect time is the amount of time required to place an off-server call,
including any greeting a caller hears. The low-usage rate and high-usage rate applies to all
line groups. The rates you set for call placement connect time apply to the entire server.
Measurement Method
Connect time other than call placement connect time is measured in tenths of minutes (6
seconds), rounded up if not exact. Call placement connect time is measured in one-minute units.
This statistic can increment to about 109 hours before the accumulator restarts at zero. This is
equivalent to about 3.5 hours per day for a month.
Calculation of Charges
When charges are calculated, they are based on minutes of connect time, rather than tenths of a
minute. This is to allow rates, which are precise to $0.001, to be adjusted by small amounts.
Disk Usage
This section explains billing for disk usage.
Measurement Method
The disk usage statistic is calculated as follows: the message size multiplied by the time on disk.
Message size is measured in tenths of a minute (6 seconds), rounded up if not exact. Time on
disk is measured in hours, rounded up to the next hour, and is calculated when the message is
deleted from the server.
The disk usage statistic resets to zero after 16,777,215 units of usage (one unit equals one-tenth
of a minute multiplied by 1 hour of storage). This is equivalent to keeping three hours of speech
for 1 year.
Calculation of Charges
Users typically accumulate several thousand units of disk usage per month, unless they delete
messages immediately after they are received. If the rate were applied to the usage as
accumulated, a rate of $.001 would be a significant charge, and the only way the rate could be
changed would be to double it. Therefore, when charges are calculated, disk usage values are
