<p>Based on the urgency, the caller ads a priority tag number while making telephone calls. The called party receives the calls with different alarm features based on the urgency of the call. The called party can set profiles rules so that calls with a lower urgency may be blocked if inconvenient. The profile rules may be altered autonomously in various circumstances. In addition a new configuration of telephone instruments is disclosed, having special keys and different alarm features, for enabling prioritization in transmission and reception of calls.</p> |
