The number is required to associate with the call. The DTMF message only contains Three user configurable bytes. So the number is the only way to match the QSL to the callsign of the sender.

*The ‘required’ exchange for a valid satellite contact would be an acknowledgement of the call sign, as most of us on the amateur satellites are grid chasers we will include our grid.
