To clarify, the usage statement shows a 33 minute call that is labeled under type as "Call Waiting". What does that mean? Was this a call on hold for 33 minutes? Or maybe a call involved with another call concurrently for 33 minutes? Please advise.
That's a really good question, mgaston! It's likely due to answering an incoming call while you were already on a call. For example, if you were talking to caller 1 when caller 2 rang in, but you disconnected the original call with caller 1, this would show-up as "call waiting" in your usage.
