I've not used it with VoIP, but we have a speakerphone which we have used on occasion in a meeting where someone was unable to attend.
When it is turned on, it sends out a 'ping' and measures the echo response of the room, and perfectly cancels out all of the echo thereafter, unless it is moved. If it is moved then the echo becomes horrible. A cheaper unit might not do echo cancellation quite as well.
