Door opener with ## doesn't work (eng)
If the built-in door opener of the Robin doesn't respond to the '##'-command on the phone, check the following two things:
1 - Is the '#' DTMF key in use for something else? In some PBXs, the '#'-key on the phone activates another function. In that case, disable this function in the PBX or select another key-combination in the configuration of the Robin. This can be done in the menu -System-Switch-
2 - On some telephone sets you need to activate the DTMF-function before it can send DTMF commands. In that case, activate DTMF before pressing the '#' key.
