Generate fastest route with set of locations

I have a set of locations, the workers need to visit this locations (view below image with points) i need to find the best possible route along this set of points no matter where does it start.

I tried with the "trip/" API but it creates new points that do not exist in the original points, and this creates a terrible route.

Am i missing something in parameters?

This is the original set of locations

And this is what returns from OSRM, clearly there are additional points, and its wrong
