This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Indicates whether or not the speakerphone functionality of the phone is enabled.
var speakerEnabled = window.navigator.mozTelephony.speakerEnabled; // Is the speaker enabled? window.navigator.mozTelephony.speakerEnabled = true; // Turn on the speaker

false indicates that it is not. You may read and write this value.
