Under the current system with names on the board to ring crewing the call often is not answered.It is not just 30 seconds at the end of a duty.At times it can take numerous calls and some 20 minutes to get an answer.I have even had the phone picked up and immediately hung up on me. If this is going to go through then how about some give and take like under no circumstances unless on a standby,contactable or you have rung in offering to sell do they ring you at home?
