Using VoIP, an enterprise positions a "VoIP device" at a gateway. The
gateway receives packetized voice transmissions from the calling party. The
Cisco AS5300 then prompts the caller for their PIN number, the entered value
is then passed onto the Radius server which performs the authentication once
confirmed, sends a request back to the Cisco AS5300 requesting that the
caller now enter the destination number. The information is then passed to
the VoIP Software Module enabled WIGWAG Billing Software product which in
turn matches the call number, rate and prepaid time left for the customer,
to it's internal rate table and passes the information back through Radius
to the Cisco AS5300. Finally, the initial process is complete and calling
party is informed of their current prepaid balance and rate of the requested
call then connected to his/her destination.
While on a prepaid call the Cisco AS5300 will use the attributes that were
passed on from the Radius Server to count down the call usage time, and will
alert the caller based on pre-defined intervals of time remaining. If the
call timer reaches a value of "0" the caller will then be disconnected.
However, if the caller disconnects prior to their time running out, the
Cisco AS5300 will send the final attributes to WIGWAG Billing and
In regards to the prepaid functionality, LogiSense Corporation offers the
WIGWAG Prepaid Billing Module which must be installed if you
are planning to offer this service to your customers.
