If I want to say sthg like, I called him twice and every time the answering machine went off at the first ring. Is that Ok?
What I mean is that when I call him, the call goes to voice mail directly without hearing a tone.? how can I say that in English without using a lot of circumloquio. Went off etc...

I called him ten times this morning, but all I got was the answering machine.

Edit: not quite the same.

I called him ten times this morning, but each time, I instantly got the answering machine (instead of the ring tone).

When do we use went off?You don't, unless you are talking of bombs or fireworks. Or alarm clocks.

When do we use went off?
In the sense of triggering: bombs, guns, alarms (including fire alarms and alarm clocks), and suchlike. But they're responding either to a pre-set timed stimulus or an unintentional one. I would consider, "He pressed a button and the bomb went off" to be badly phrased.

Here the answering machine is responding immediately to a intentional action. Additionally, answering machines are often personified: e.g. "the answering machine picked up".
