2) ACU-1000 greets the PSTN caller and prompts him to enter the “star” and two-digit
number of the extension that caller would like to converse with. In our example,
User A resides at extension 03, so PSTN caller enters * 0 3.

CONNECTED” to the PSTN caller indicating the connection has been successfully
completed.
4) PSTN caller and User A talk. At the end of conversation, either user can terminate
the link by entering * #. In links involving more than two modules, all users should
terminate the link by using * #.
