IP phone audio test
IP telephones have been developed from the previous computer-to-computer voice for being online simultaneously at the agreed time and are now integrated with the telephone network, simplifying the network communications. Its wide range of commercial applications has also increased the requirements for voice. Special electroacoustic testing equipment is required for quantitative detection.

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
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
