Call Forwarding Agent

Sammanfattning: In today’s world of telecommunications there is an increasing problem with reaching people one wishes to speak to. People have several telephones and this makes the situation complex for the caller. Many phone calls are left unanswered. The Call Forwarding Agent is in this report presented as a solution to this reachability problem. The idea is to have an agent setting call forwards of all the users’ phones or numbers, towards the terminal where he is available. Later, when someone calls any of the users’ phones, the call will be terminated at the terminal where the user can receive it. The Call Forwarding Agent is compared to a number of similar services. The personal number service offers the same functionality as the Call Forwarding Agent, but the Call Forwarding Agent does not force the subscriber to change phone number and it also admits a simple call screening. We have implemented a prototype of the Call Forwarding Agent that can set call forwards of regular Public Service Telephony Network terminals and the Internet telephones in Ellemtel’s IP-phone system.
