Auto Provisioning of Telephony Equipment Dustin Hatfield CIS 597

Background CustomerMaster  Customer information is stored in this third-party database system  Customer's current and requested service details as well as their plant records  Entered and edited by the customer service and plant department personnel, through an existing graphical interface  Requests for changes in service are handled by service orders  CSRs creates the service order and it is sent to the necessary personnel to provision the requested changes.

Background DMS-10  Telephone service is provided by a telephony switch  DMS has a command line interface for provisioning AP Unit  Advanced telephone features; voic , caller-id database, etc.  AP unit does not have an API or CLI available for provisioning, and will require packet sniffing to reverse engineer the communications necessary to provision it
