SipAudioCall

public class SipAudioCall
extends Object

java.lang.Object
↳	android.net.sip.SipAudioCall

Handles an Internet audio call over SIP. You can instantiate this class with SipManager, using SipManager#makeAudioCall and SipManager#takeAudioCall.

Note: Using this class require the Manifest.permission.INTERNET and Manifest.permission.USE_SIP permissions. In addition, startAudio() requires the Manifest.permission.RECORD_AUDIO, Manifest.permission.ACCESS_WIFI_STATE, and Manifest.permission.WAKE_LOCK permissions; and setSpeakerMode() requires the Manifest.permission.MODIFY_AUDIO_SETTINGS permission.

For more information about using SIP, read the Session Initiation Protocol developer guide.

SipManager.isVoipSupported(Context)

close

public void close ()

Sends a DTMF code. According to RFC 2883, event 0--9 maps to decimal value 0--9, '*' to 10, '#' to 11, event 'A'--'D' to 12--15, and event flash to 16. Currently, event flash is not supported.

Parameters
`code`	`int`: the DTMF code to send. Value 0 to 15 (inclusive) are valid inputs.

setListener

public void setListener (SipAudioCall.Listener listener, 
                boolean callbackImmediately)

Sets the listener to listen to the audio call events. A SipAudioCall can only hold one listener at a time. Subsequent calls to this method override the previous listener.

Parameters
`listener`	`SipAudioCall.Listener`: to listen to the audio call events of this object
`callbackImmediately`	`boolean`: set to true if the caller wants to be called back immediately on the current state

setListener

public void setListener (SipAudioCall.Listener listener)

Sets the listener to listen to the audio call events. The method calls setListener(listener,false).

Parameters
`listener`	`SipAudioCall.Listener`: to listen to the audio call events of this object

See also:

setListener(Listener, boolean)

setSpeakerMode

public void setSpeakerMode (boolean speakerMode)

Puts the device to speaker mode.

Note: Requires the Manifest.permission.MODIFY_AUDIO_SETTINGS permission.

Parameters
`speakerMode`	`boolean`: set true to enable speaker mode; false to disable

startAudio

public void startAudio ()

Starts the audio for the established call. This method should be called after Listener#onCallEstablished is called.
