I started a voluntary prayer, then the congregational prayer was called for while I was in the first rak'ah. What is obligatory for me?

The questioner:
Honorable Shaykh, may Allah grant you success. The questioner says: What is obligatory for me if I had started a voluntary prayer, and then the prayer was called for while I was in the first rak'ah of the voluntary prayer? Do I cut it off?
The Shaykh:
If you can shorten it and conclude it before the imam bows, complete it. But if the imam is bowing and you have not completed it, cut it off. Yes.
The presenter:
Then he says, may Allah preserve you,
The questioner:
And when I cut it off, do I say the taslim to my right and to my left?
The Shaykh:
You did not complete it; the taslim is upon completion. You did not complete it; its conclusion is the taslim. Yes.
