From: Daniel Wagner <[email protected]>
And instead fallback using the configuration plugin for
selecting the emergency application.
Now we don't have to update all other sessions which makes
the whole code logic more straight forward. If a session is
markes as emergency call and this application calls Connect()/Disconnect()
it will succedd and block all other session when they try to call
Connect() of Disconnect().
