As apparatus for responding silently to incoming calls in a communication system. Such an apparatus provides the capability to respond to incoming calls in the communication system which could be, for example, a telephone system, for those cases necessitating minimal disruptions such as wherein the telephone user receiving the call is in a meeting or other group situation. With the system disclosed herein, the telephone user can respond to the caller immediately with pre-recorded responses. Special responses can be pre-recorder for special situations or special callers.

Interactive pre-programmed voice response system

In various embodiments of the present invention, execution-state transitions occur in a first portion of a system, and a cumulative execution state for each process is maintained by a second portion of the system so that, when a second-portion routine is called, the second-portion routine can determine whether or not the current execution state is suitable for execution of the second-portion routine. In various embodiments, a callpoint log, allocated and maintained for each process, stores the cumulative execution state for the process. In one embodiment, the first portion is an operating system, and the second portion is a secure kernel, with the cumulative execution state used by the secure kernel to prevent unauthorized access by erroneously or maliciously invoked operating-system routines to secure kernel routines. In another embodiment, the cumulative execution state is used as a debugging tool by the second-portion routines to catch errors in the implementation of the first-portion routines.
