the VMail functionality is great. But VMail could be too long to be transmittedon the calling frequency. So, when the receiving station is not occupied ("I am away" switched on ), the sender should be able to initiate a QSY after connection, and the receiving station should follow the QSY request automatically. This process would free up occupation time on the calling frequency.
Of course the receiving station should then go back to the calling frequency automatically, just after the delivery of the VMail.
