What we need is the following:
When someone calls “us??, with his or her number ID turned on, the specified number needs to be analysed, resulting in a possible call to another number. This analysis consists of;
Keeping a database (we could start with Acces, - depending on amount of users- we may need to turn it into a SQL Database) in which we keep track of the following (record definition):
· *“called-by?? numbers*,
· *“forward-to?? numbers*,
· *time restraints* (consisting of *“from Date??* and *“till Date??*)
1. When our telephone (ISDN) receives a call, the program needs to *read* the callers number (from the ISDN card)
2. The database needs to be checked in order to determine if this number is *known* (*called-by numbers* FIELD)
a. If the number is known (= already stored in DB), a check needs to be made for the related *forward-to number.*
3. Then the related *time restraints* need to be compared with the current local time in order to find out if a forward is ALLOWED (= if current local time falls within range of *from date* and *till date*)
a. If forwarding is ALLOWED, the already specified *forward-to number* needs to be called through one of our other ISDN-connected lines.
Shortly, SUCCES is:
somebody calls our number 1234567, the callers number is recognized in our DB, time of calling falls within time restraints ? forward-to number is called from our other number 7654321.
*incoming caller needs to be recognized OFF- HOOK (caller should not be charged for calling us)
