Single room with a window, priceless. I would try it during lunch time, out going call only.

中英文别人都听得懂。完全没有privacy

car是个好主意，但是欧的车停在巨远要坐shuttle的parking lot, 不然的话车里真的是最理想的地方了

lunch hour, yes, 其实关键不是时间而是地点，接个电话肯定在半小时以内一般不会被发现，但是如果没有安静隐蔽的地方，难道专门回次家接电话，那样两三个小时就进去了，肯定县的行踪可疑

There're several conference rooms in our company, if I need to make a private call, I'll just go find one which is not in use.
