  • Call admission control in telecommunication networks
    Patent number: 6909690
    Abstract: A communication hub that controls access to a communication network over a communication path based on silence suppression. The communication hub comprises a silence suppression block, a call admission block, and a control system. The silence suppression block is configured to compute a silence suppression gain for an incoming call based on a silence suppression realized for the incoming call and a number of currently active calls. The call admission block is configured to control access to a communication network over a communication path based on the silence suppression gain for the incoming call. The control system is configured to determine a call type of the incoming call and control the silence suppression block and the call admission block.

  • Call tones in communication networks
    Patent number: 6731738
    Abstract: A communication hub for providing call tones in a communication network proximate the calling device. The communication hub comprises an interface coupled to a processor and a tone generator. The tone generator is configured to generate call tones. The processor is configured to process an in-band call tone request message to direct the tone generator to provide the call tones to a call device. The interface is configured to receive the call tone request message and provide the call tones to the call device.

  • Continuity testing with call tone messaging in communication networks
    Patent number: 6728362
    Abstract: A communication hub for providing continuity testing and call tones in communication networks. The communication hub comprises a processor coupled to an interface and a tone generator. The processor is configured to process an in-band call tone request message to generate a continuity acknowledgment message and to direct the tone generator to provide call tones to a call device. The tone generator is configured to generate the call tones for the processor. The interface is configured to receive the call tone request message and transmit the continuity acknowledgment message and the call tones for the processor.
