Control telephone calls from the browser, yes browser! But Mozilla Mobile Browser as of now.

The phone functionality can be used with the help of navigator.mozTelephony , which is part of the WebTelephony API.

P.S : This is a nonstandard API and is subjected to change and works only with Firefox Mobile (Gecko) 12.

Here is a simple code example of playing with the mozTelephony API :

// Telephony object var tel = navigator. mozTelephony ; // Check if the phone is muted (read/write property) console. log ( tel. muted ) ; // Check if the speaker is enabled (read/write property) console. log ( tel. speakerEnabled ) ; // Place a call var call = tel. dial ( "123456789" ) ; // Events for that call call. onstatechange = function ( event ) { /* Possible values for state: "dialing", "ringing", "busy", "connecting", "connected", "disconnecting", "disconnected", "incoming" */ console. log ( event. state ) ; } ; // Above options as direct events call. onconnected = function ( ) { // Call was connected } ; call. ondisconnected = function ( ) { // Call was disconnected } ; // Receiving a call tel. onincoming = function ( event ) { var incomingCall = event. call ; // Get the number of the incoming call console. log ( incomingCall. number ) ; // Answer the call incomingCall. answer ( ) ; } ; // Disconnect a call call. hangUp ( ) ; // Iterating over calls, and taking action depending on their changed status tel. oncallschanged = function ( event ) { tel. calls . forEach ( function ( call ) { // Log the state of each call console. log ( call. state ) ; } ) ; } ;

Hope this becomes a standard in all Mobile Browser one fine day! Anyway cheers to Mozilla team from making this API!
