It seems that after I transitioned his airspace (and had
switched to another frequency) he had tried to contact me, because he
wanted
to make sure I was clear before releasing an IFR departure.
Are you not supposed to ask for a frequency change before you leave them?
Or just let them know you're leaving the frequency?
