1.2 Executed tests

The tests were classified into

  • Installation and configuration
  • Accepting and terminating calls
  • Mute
  • Volume control
  • Unplug and replug of USB adapter

The tests completed successfully; the different test PCs or operating systems did not influence the test results.

1.3 Restrictions

The following restrictions were detected during the tests:

  • The Calisto P620 must be configured as a headset in the SwyxIt!
  • During an incoming call, only the configured Plantronics ringtone will be played into the Calisto P620. The volume of the ringtone can only be adjusted on the Calisto P620, but not by the SwyxIt! sliders.
  • The audio volume can only be adjusted on the Calisto P620, but not by the SwyxIt! sliders.
  • It is not possible to mute the SwyxIt! by the Calisto P620 during an incoming call or in idle state.
  • If the SwyxIt! is muted by the SwyxIt! control during an incoming call or in idle state, the Calisto P620 does not reflect this. In this case, if the call is accepted or during call establishment, the call is muted and the Calisto P620 reflects this correctly.
  • If the USB adapter is unplugged during an active call, the call gets terminated. After replugging the USB adapter, the Calisto P620 indicates that a call is still active. The call control button on the Calisto P620 must be pressed twice in order to syncronise the call state, otherwise, the first call wouldn't have any payload.
  • After answering an incoming call may take up to two seconds until the voice connection is established. Two additional seconds are necessary until the microphone is calibrated. This delay also occurs during the calibration of the microphone or when recording an announcement for the voicemail.

1.4 Ringing Tones

During in incoming call, only the configured Plantronics ringtone will be played into the Calisto P620. It is not possible to play the specific SwyxIt! ringtone into the Calisto P620.

If additional ringing on the internal speaker is configured both via the Plantronics Controlpanel and the SwyxIt!, these ringtones will interfere.

Install Plantronics Spokes Software for SwyxIt!/NetPhone.
