Cisco CVP plays audio media files to callers during IVR interactions. These files must conform to specific technical specifications to be supported by CVP and properly rendered by the VVB or VXML gateway.
Why the Correct Answer is Right: B is correct because CVP supports G.711 mu-law (North America/Japan) and G.711 a-law (Europe/international) encoding for audio files. These are the two standard PCM codec variants used in telephony audio, documented in the Cisco CVP Administration Guide. E is correct because the required audio file format for CVP media files is WAV (.wav). The file must be in a specific WAV format (8kHz, 8-bit, mono) to be properly played by the IVR system.
Why Each Incorrect Answer is Wrong: A is wrong because MP3 format is not supported by Cisco CVP for media files—MP3 uses lossy compression incompatible with CVP's media rendering requirements. C is wrong because while G.729 is a valid VoIP codec for call compression, CVP media files must be in G.711 format. D is wrong because the maximum media file size of 40 MB is not a documented official CVP constraint.
