A wireless handset or other communication device includes a user interface implemented with a display and a number of select buttons. The display provides an array of identifiers arranged in rows and columns, with the identifiers corresponding generally to lines or functions of a communication system. The display also provides a status indication for each of the identifiers. A status indicator for a line identifier may indicate whether the corresponding line is in use by the handset user, in use by another system user, or idle, while a status indicator for a function identifier may indicate whether the function is activated or deactivated by the handset user. The assignment of identifiers to lines or functions may be in accordance with a mapping from a wired system, and the status information may be supplied to the handset from a switch of the wired system. The handset includes at least one row select button for selecting a particular one of the rows of identifiers provided in the display, and at least one column select button for selecting a particular one of the columns of identifiers. The selection of a particular row and column indicates selection of a line or function associated with the corresponding identifier. The display may be configured such that all of the identifiers and the state of their corresponding status indicators are visible to the user whenever the handset is on.

Display-based interface for a communication device

A system and method for testing communication devices, such as speakerphones, are disclosed. In one embodiment, a two-way conversation is pre-recorded for playback through one or more test communications devices to evaluate communications device performance. The test set-up permits the recording of a two-way full-duplex communication onto two or more channels of the same recording/playback device, thereby preserving the content and timing relationships between speech segments. A comparison can be made between the live conversation and the conversation as it was realized in the playback condition over a test communications device. The original and the test will be different based on the performance of the communications device. This method decreases the test time and provides other efficiencies useful in connection with testing, evaluation and quality control for communications device acoustic and network performance testing.
