1 <HTML> 2 <BODY> 3 <p>Provides access to Session Initiation Protocol (SIP) functionality, such as 4 making and answering VOIP calls using SIP.</p> 5 6 <p>For more information, see the 7 <a href="{@docRoot}guide/topics/connectivity/sip.html">Session Initiation Protocol</a> 8 developer guide.</p> 9 {@more} 10 11 <p>To get started, you need to get an instance of the {@link android.net.sip.SipManager} by 12 calling {@link android.net.sip.SipManager#newInstance newInstance()}.</p> 13 14 <p>With the {@link android.net.sip.SipManager}, you can initiate SIP audio calls with {@link 15 android.net.sip.SipManager#makeAudioCall makeAudioCall()} and {@link 16 android.net.sip.SipManager#takeAudioCall takeAudioCall()}. Both methods require 17 a {@link android.net.sip.SipAudioCall.Listener} that receives callbacks when the state of the 18 call changes, such as when the call is ringing, established, or ended.</p> 19 20 <p>Both {@link android.net.sip.SipManager#makeAudioCall makeAudioCall()} also requires two 21 {@link android.net.sip.SipProfile} objects, representing the local device and the peer 22 device. You can create a {@link android.net.sip.SipProfile} using the {@link 23 android.net.sip.SipProfile.Builder} subclass.</p> 24 25 <p>Once you have a {@link android.net.sip.SipAudioCall}, you can perform SIP audio call actions with 26 the instance, such as make a call, answer a call, mute a call, turn on speaker mode, send DTMF 27 tones, and more.</p> 28 29 <p>If you want to create generic SIP connections (such as for video calls or other), you can 30 create a SIP connection from the {@link android.net.sip.SipManager}, using {@link 31 android.net.sip.SipManager#open open()}. If you only want to create audio SIP calls, though, you 32 should use the {@link android.net.sip.SipAudioCall} class, as described above.</p> 33 34 <p class="note"><strong>Note:</strong> 35 Not all Android-powered devices support VOIP functionality with SIP. Before performing any SIP 36 activity, you should call {@link android.net.sip.SipManager#isVoipSupported isVoipSupported()} 37 to verify that the device supports VOIP calling and {@link 38 android.net.sip.SipManager#isApiSupported isApiSupported()} to verify that the device supports the 39 SIP APIs. 40 Your application must also request the {@link android.Manifest.permission#INTERNET} and {@link 41 android.Manifest.permission#USE_SIP} permissions in order to use the SIP APIs. 42 </p> 43 44 </BODY> 45 </HTML>
