When a telephone subscriber is not at home, he is not aware of incoming calls. Up to now several features have been used, if there is no reply to a phone call:  Call Forwarding on No Reply to any number  Call Forwarding on No Reply to Voice Mail Service  Call Completion on No Reply The disadvantages of these features are that the subscriber is charged for the second leg of the call (first feature), or that the mobility is not supported (second and third feature). The new solution for that problem proposes to inform the absent subscriber about each incoming call via Short Message Service (SMS) to his/her mobile phone. This is possible because SMS is recently available for PSTN (Public Switched Telephone Network). The number of the calling party can also be included to the SMS.

Another subscriber B calls the subscriber A. After the expiration of the No Reply timer, the call is released and a SMS is sent automatically to the mobile phone including the calling number of subscriber B. The subscriber A receives this SMS and decides whether to call back subscriber B from his mobile phone or from another line or not to call back at all. Possible variations of the SMSNR concept are:
