Claim:
A data processing and communications device, comprising at least one data processor configured to execute machine-interpretable instructions for causing the device to: generate, using command signals received from at least one input device, a signal set representing a meeting request, the meeting request signal set comprising signals representing one or more parameters for a proposed meeting and configured for causing a second data processing and communications device to initiate a voice call on receipt of command signals representing a response to the meeting request, when the response is other than an accept response; forward the generated meeting request signal set to the second data processing and communications device; receive a signal set representing a non-voice data set representing the response to the meeting request, the non-voice data set including information about the response to the meeting request; determine that the signal set representing the non-voice data set was received in absence of a signal set representing establishment of the voice call; in response to the determination, generate signals for indicating that an attempt to establish the voice call was unsuccessful; and store reply information data containing information about the non-voice data set.
