When customer ends the call just before agents, they will get this Release AMCAdapter error message. In this very case only, can we silent the error message and do not popup any error or message and let the solution release or clear the call session/handle when user click on Release button in CTI Toolbar.
However, we have seen the same Release AMCAdapter error message on several cases. ie, when call was made and disconnect immediately, when call reached to VM and disconnect; when the call got into busy signal and disconnect, when the call was invalid and disconnect. Those cases were producing the same error messages and we do not want to silent the popup error.
