    Solution introduction
    IP phone host test in hands-free state

    IP phone host test in hands-free state

    • The IP phone communicates with the CRY6151B through the network to make the IP phone's main speaker sound → artificial auricle and artificial ear for signal acquisition → input into CRY6151B through the MIC channel for test analysis

    • CRY6151B uses the MOUTH interface to output signal and control the sound of the mouth simulator → IP phone host MIC collects sound signals → connecting to CRY6151B for analysis through the network

    IP phone handle test

    IP phone handle test

    • CRY6151B connects with the handle through the HEADPHONE interface to make the speaker sound → measure the microphone to collect the signal → input into CRY6151B from the MIC channel for test and analysis

    • CRY6151B uses the MOUTH interface to output signal and control the sound of the mouth simulator → the handle collects sound signals → input into CRY6151B for analysis through the HEADPHONE interface
