Abstract
A third-party call setup gateway (90) is provided for setting up bearer channels (60) through a switched telecommunications system, such as a PSTN, by controlling an associated switch (41). The call setup gateway (90) has an interface onto a computer network, such as the Internet, that is accessible to users of the telecommunications system. In a preferred arrangement, a user A wishing to place a call to user B gets the details of B's current telephone number from a “phone page” (41) on B's website and then sends this telephone number together with A's own telephone number, to the gateway (90). The gateway (90) then commands the switch (41) to establish a call between A's telephone and B's telephone.
