Audio format selection
After the IP Deskphone receives the endpoint configurations, it searches the records to select an audio format that matches the IP Deskphone requirements. If no match is found, then the default audio format is used. After you select the format, the IP Deskphone sends a command to the device to select the corresponding endpoints for audio transfers.
The IP Deskphone supports both 8KHz and 16KHz audio. You can select the 16KHz audio, if the headset supports it. The IP Deskphone is a mono device with only one voice channel. For stereo USB headsets detected, the IP Deskphone replicates one channel voice data to both left and right channels of the headsets to simulate stereo output.The following table lists the audio format requirements supported by the IP Deskphone.
