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.
