GR translation: get on to the operations room

[Mike Jing]

P7.18-23   Oughtn’t he to be doing something . . . get on to the
operations room at Stanmore, they must have it on the Channel
radars—no: no time, really. Less than five minutes Hague to here (the
time it takes to walk down to the teashop on the corner . . . for
light from the sun to reach the planet of love . . . no time at all).
Run out in the street? Warn the others?

What is "get on to"?  Does it mean to get on the phone?
