A system and method for feature-based service control using Session Initiation Protocol (SIP) in an Internet Protocol Automatic Branch Exchanges (IPABX) system is described. The system and method include a new Event package and new Enhanced SIP methods to control information for various feature-based services like wakeup alarm, call forwarding, voicemail configuration, and other services provided by traditional PBX systems. A user provides input to a client device to activate or deactivate feature-based services. In response, the client device sends a message to the IPABX server to activate or deactivate the feature-based service(s). The IPABX server then notifies the client device that the feature based-service(s) have been activated or deactivated.

A method for management and control of a media session. The method comprises receiving a first message from an end user device at an application server to initiate a media session and forwarding the first message from the application server to a media server. A first media transaction between the media server and the end user device is then conducted. The method further comprises, receiving a second message from the media server at the application server to indicate that the first media transaction is complete. The method still further comprises transmitting a third message from the application server to the media server to initiate a second media transaction and conducting the second media transaction. After the second media transaction is complete, the method comprises and receiving a fourth message from the media server at the application server indicating that the second media transaction is complete.

Disclosed is a method and apparatus for software configuration of a processor clock ratio. Boot code that the processor executes in response to a reset event correctly configures the clock ratio to a desired value, where the desired value can be set via a user interface. The processor then checks the clock ratio against a desired clock ratio value stored in a nonvolatile memory. If the clock ratio is the same as the desired clock ratio value, then the processor completes the boot of the processor. If the clock ratio is different from the desired value, then the processor writes the desired value into a latch connected to the on clock configuration input terminals of the processor and inhibits reset of the latch. The processor then generates another reset event. In this reset cycle, the processor will sense the desired clock ratio value driven onto the clock configuration input terminals by the latch and boot with the desired clock ratio.

A system for shutting down and resetting an embedded system having a general purpose computing platform. A push button is provided for generating a push button reset signal to the shutdown and reset manager. The shutdown and reset manager receives the management reset signal and initiates a shutdown of the operating system. When the operating system has shutdown, the user presses the push button again. The second receipt of the push button reset signal initiates a hardware reset.

Push button shutdown and reset of embedded systems

A system for shutting down and resetting an embedded system having a general purpose computing platform. A shutdown management driver generates a management reset according to a predetermined set of shutdown conditions. The shutdown and reset manager receive the management reset signal and initiate a shutdown of the operating system. When the operating system has shutdown, the second receipt of the management reset signal initiates a hardware reset.

Disclosed is a system and method for supplying power to multiple devices using a single voltage regulator. The present invention includes a comparator that compares the voltage identification codes from multiple devices in a system. If all the devices have the same value for the voltage identification code, then the comparator forwards the code to a voltage identification input of a programmable voltage regulator, which then outputs a power supply voltage at a level corresponding to the voltage identification code value of the devices. If any device present in the system has a different value for its voltage identification code, then the comparator outputs a predetermined value to the programmable voltage regulator that prevents the voltage regulator from outputting a power supply voltage.
