I want to develop a SMS gateway small application,
for delivering a message from incoming SMS or email,
to responsible Person In Charge (PIC) via outgoing SMS.
The incoming messages should be parsed to obtain the information,
after we get the information, then the application look a corresponding
message that have to delivered, and send the message by SMS to the PIC.
If the PIC receive the SMS, he should reply twice.
One is for acknowledgment, and the other is if the requested job
has been done.
If the PIC do not response to the message, then the application
will send the message to supervisor of the PIC, and can be
escalated to supervisor of the supervisor.
