Abstract

A system is provided for automated configuration of a connection interface between a headset device (e.g., a headset base) and a telephone (e.g., desktop phone). The system includes configuration circuitry designed to automatically perform a sequential analysis of multiple interface configuration options for the connection interface between the headset device and telephone. The analysis of each respective interface configuration option includes (a) accessing stored configuration information defining predefined switch positions for an array of controllable switches (e.g., optical switches) corresponding with the respective interface configuration option, (b) set the array of switches to the predefined switch positions specified by the accessed configuration information, and (c) performing a signal analysis to analyze electrical signals on the connection interface. The configuration circuitry may then select a best interface configuration option based on the signal analyses, and set the switches to the predefined switch positions corresponding with the selected best interface configuration option.
