I don't recall 2s latency, but do remember 0.25-0.3s latency one way for transatlantic phone calls in the 90s, which happens when the call got related over geostationary satellites rather than over Atlantic cables. It was basically a 0.5-0.6s roundtrip delay enough to cause you to talk over each other.

It only happened when there were too many callers at the same time. The solution was often to redial and hoping you ended up with a non-satellite call.
