"No Device" error message on client start

Recently I wanted to avoid that the infolog pops-up with several

‘No Device’

error messages when opening the AX client with ConfigKey Telephony Integration enabled.

This error message is caused by the ActiveX component for the phone integration on form smmPhone which returns an error for each phone device which is offline.

I did the following code changes to prevent the error message:

void onEvent_TapiError(int errorCode)
    if(errorCode != -2147483582) // Avoid 'No Device' Error
