InitialNumberProcess(Headcode)
In order to identify phone numbers from the phone book or customer database, you have to delete or cor-
rect some abnormal Caller IDs and dialed numbers that have the telecom service head-code.
Incoming Head-codes
For example, consider Caller ID: 075528282828. If you have set the area code in the Incoming head-
codes, then the system will remove 0755, and search only 28282828 in the customer database (customer.
zcsm). So it can popup the client information corresponding to the telephone no. ‘28282828’ from the da-
tabase.
Outgoing Head-codes
For example, you are Dialing out 1790901022222222. Here 17909 is the headcode for the telecom long
distance call service. The system has to Filter this head-code to search the correct information in the cus-
tomer database (customer.zcsm).
