man kann es einstellen, dass das Gerät beim ACK etwas anderes schickt. Das macht durchaus Sinn, da wir beim Invite mit langen Namen agieren können, welche das Telefon schön über mehrere Zeilen darstellt. So kann man im Ringing schon wichtige Informationen zu dem Alarm auf das Display bringen. Beim Connect wird die Anzeige ja auf eine Zeile reduziert und so wird nicht mehr alles dargestellt. Hier wäre es ja nun schön, wenn noch die wichtigen Informationen (z.B. Ort der Alarmauslösung) angezeigt würden und nicht die weniger interessanten Teile der langen Anzeige.
