/**
* Provides APIs for SIP tasks, such as initiating SIP connections, and provides access to related
* SIP services. This class is the starting point for any SIP actions. You can acquire an instance
* of it with {@link #newInstance newInstance()}.
* The APIs in this class allows you to:
*
* - Create a {@link SipSession} to get ready for making calls or listen for incoming calls. See
* {@link #createSipSession createSipSession()} and {@link #getSessionFor getSessionFor()}.
* - Initiate and receive generic SIP calls or audio-only SIP calls. Generic SIP calls may
* be video, audio, or other, and are initiated with {@link #open open()}. Audio-only SIP calls
* should be handled with a {@link SipAudioCall}, which you can acquire with {@link
* #makeAudioCall makeAudioCall()} and {@link #takeAudioCall takeAudioCall()}.
* - Register and unregister with a SIP service provider, with
* {@link #register register()} and {@link #unregister unregister()}.
* - Verify session connectivity, with {@link #isOpened isOpened()} and
* {@link #isRegistered isRegistered()}.
*
* Note: Not all Android-powered devices support VOIP calls using
* SIP. You should always call {@link android.net.sip.SipManager#isVoipSupported
* isVoipSupported()} to verify that the device supports VOIP calling and {@link
* android.net.sip.SipManager#isApiSupported isApiSupported()} to verify that the device supports
* the SIP APIs. Your application must also request the {@link
* android.Manifest.permission#INTERNET} and {@link android.Manifest.permission#USE_SIP}
* permissions.
*
*
* Developer Guides
* For more information about using SIP, read the
* Session Initiation Protocol
* developer guide.
*
* @deprecated {@link android.net.sip.SipManager} and associated classes are no longer supported and
* should not be used as the basis of future VOIP apps.
