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 SipManager.NewInstance(Android.Content.Context).

The APIs in this class allows you to:

• Create a Android.Net.Sip.SipSession to get ready for making calls or listen for incoming calls. See SipManager.CreateSipSession(SipProfile, .Listener) and SipManager.GetSessionFor(Android.Content.Intent).
• Initiate and receive generic SIP calls or audio-only SIP calls. Generic SIP calls may be video, audio, or other, and are initiated with SipManager.Open(SipProfile). Audio-only SIP calls should be handled with a Android.Net.Sip.SipAudioCall, which you can acquire with SipManager.MakeAudioCall(SipProfile, Android.Net.Sip.SipProfile, Android.Net.Sip.SipProfile, Android.Net.Sip.SipProfile) and SipManager.TakeAudioCall(Android.Content.Intent, .Listener).
• Register and unregister with a SIP service provider, with SipManager.Register(SipProfile, System.Int32, System.Int32) and SipManager.Unregister(SipProfile, Android.Net.Sip.ISipRegistrationListener).
• Verify session connectivity, with SipManager.IsOpened(string) and SipManager.IsRegistered(string).

Note: Not all Android-powered devices support VOIP calls using SIP. You should always call SipManager.IsVoipSupported(Android.Content.Context) to verify that the device supports VOIP calling and SipManager.IsApiSupported(Android.Content.Context) to verify that the device supports the SIP APIs. Your application must also request the NoType:android/Manifest$permission;Href=../../../../reference/android/Manifest.permission.html#INTERNET and NoType:android/Manifest$permission;Href=../../../../reference/android/Manifest.permission.html#USE_SIP permissions.
