IPFX Director Softphone is a computer program that emulates a physical telephone and is IPFX Director dependant. It is offered as an alternative to a physical IP phone, such as a Cisco 7940 or 7960 phone.
In order to emulate a physical telephone IPFX Director Softphone requires that your computer have both a microphone and a speaker device installed and functioning correctly. It also requires access to the IPFX Director server via a network. This means that an installed and correctly functioning Network Interface Card (NIC) or modem is required, and that the device functions correctly over an IP network.
