We needed a way to upload phonebooks to our server. We decided to use

Common Gateway Interface (CGI) to achieve this task. CGI allows for an

easy way to create an upload field and the back end functionality required to

Response (IVR) capabilities which allowed for number-pad (DTMV) input

and voice response. It also let use create a response sequence based on the

users’ inputs. In addition, the software had modules to connect to a server,

download a file, and read from a Comma Separated Values (CSV) file. This

was used to download phonebooks in CSV format from the web-server and

store it on the local voicemail machine for use by the software.

We needed a modem for the voicemail part of the system. The NCH

software required that the modem be Telephone Application Programming

Interface (TAPI) compliant. The two overall options for this modem were
