Abstract: Disclosed is a communication device (102) that can be hosting a communication application (112) and/or software, such as PTT/VoIP application, which is at least partially controlled and supplemented with payload data by at least one accessory to provide remote UI capabilities, to be used in a communications system as system element, with an UI feature and/or accessory device for communicating commands, signaling data and/or voice/audio data. Also disclosed is an accessory device as a system element of the communications system.

Abstract: A mobile arrangement (102), such as a mobile communication device, including a user interface (UI) configured to receive user input, a wireless data transfer interface configured to receive a command, such as a PTT (Push-to-Talk) command, sent by an RSM (Remote Speaker Microphone) device (104a, 104b) or other accessory, such as an in-car device or a headset, wirelessly connected to the mobile arrangement, and an interfacing logic (114) configured to map the received command to a predetermined command locally providable via the user interface to a communication application (112) running on the mobile arrangement and capable of receiving user input via the user interface so as to enable utilization of the communication application through the RSM or other accessory. Corresponding method and computer program product are presented.
