I can understand that, from their point of view.
In the UK, only Solent CG operate a direct call 67 "desk" - all other MRCC's (there aren't any MRSCs anymore) listen on Ch16. This is not always done by a person either - headset watch ceased a while back, and voice recognition software monitors Ch16 for certain pro-words before routing to a loudspeaker in the ops room.
In terms of who you speak to, the old Ch16 only desk also went...and with the ability to re-route arials, you might well be talking to someone with the callsign Milford Haven CG only to find out they're at MRCC Swansea or Holyhead if the station you called is busy.
And if you're on Inmarsat, you get Falmouth no matter what!!
