Ever heard of Occam's Razor? The simplest cause of a problem is usually correct.

A...there is a tech monitoring the line and when a call is transferred he flicks his test set on and off hook and drops the call.

B...the line is attached to a malfunctioning alarm system that is going on and off hook or dragging down the line current thus dropping the call.

C...a transferred call is ringing on a set, the person receiving the call, goes off hook, presses the flashing line key, not knowing they have answered the call by simply going off hook, and when they press the line button they disconnect the caller.
