Switching telecommunications connection between two subscribers via telecommunication network, by providing alternative call numbers and/or automatically routing call if connection fails

摘要

In the event of a failed attempt at switching a connection to a second subscriber, the first subscriber is connected to a switching system in the telecommunication network, which gives the first subscriber at least one alternative call number associated with the non-switched call number, and/or automatically routes to a call number. An Independent claim is included for a system for switching a telecommunications connection.
