You seem to have received only a very negative reaction for some reason that I cannot fathom, with pointless comment about cost (totally unknown) and practicality of using a mobile phone in an Ops Room (it would hardly be engineered or approved thus!).
Surely this perfectly practical and useful suggestion could be implemented, in the UK via D&D, for the few isolated occasions when it might be required. It's not as if every unit and ACC sector would require it.
Why not take up the suggestion through your national Authority? Mind you, some of your current reported problems do seem to be within your (pilots') court!
