* mobile network call in a video calling app. The mobile network call via the Telephony stack
* is referred to as the source of the handover, and the video calling app is referred to as the
* destination.
* <p>
* When considering a handover scenario the <em>initiating</em> device is where a user initiated
* the handover process (e.g. by calling {@link android.telecom.Call#handoverTo(
* PhoneAccountHandle, int, Bundle)}, and the other device is considered the <em>receiving</em>
* device.
* <p>
* For a full discussion of the handover process and the APIs involved, see

* accept the handover of an ongoing call to another {@link ConnectionService} identified by
* {@link PhoneAccountHandle} destAcct. For managed {@link ConnectionService}s, the specified
* {@link PhoneAccountHandle} must have been registered with {@link #registerPhoneAccount} and
* the user must have enabled the corresponding {@link PhoneAccount}. This can be checked using
* {@link #getPhoneAccount}. Self-managed {@link ConnectionService}s must have
* {@link android.Manifest.permission#MANAGE_OWN_CALLS} to handover a call to it.
* <p>
* Once invoked, this method will cause the system to bind to the {@link ConnectionService}
* associated with the {@link PhoneAccountHandle} destAcct and call
* (See {@link ConnectionService#onCreateIncomingHandoverConnection}).
* <p>
* For a managed {@link ConnectionService}, a {@link SecurityException} will be thrown if either
* the {@link PhoneAccountHandle} destAcct does not correspond to a registered
* {@link PhoneAccount} or the associated {@link PhoneAccount} is not currently enabled by the
* user.

* the calling app does not have {@link android.Manifest.permission#MANAGE_OWN_CALLS}.
