A complete and systematic treatment of signal processing for VoIPvoice and fax
This book presents a consolidated view and basic approach tosignal processing for VoIP voice and fax solutions. It providesreaders with complete coverage of the topic, from how things workin voice and fax modules, to signal processing aspects,implementation, and testing. Beginning with an overview of VoIPinfrastructure, interfaces, and signals, the book systematicallycovers:
* Voice compression
* Packet loss concealment techniques
* DTMF detection, generation, and rejection
* Wideband voice modules operation
* VoIP Voice-Network bit rate calculations
* VoIP voice testing
* Fax over IP and modem over IP
* Country deviations of PSTN mapped to VoIP
* VoIP on different processors and architectures
* Generic VAD-CNG for waveform codecs
* Echo cancellation
* Caller ID features in VoIP
* Packetization--RTP, RTCP, and jitter buffer
* Clock sources for VoIP applications
