When I answered a call from this number, there was a long delay with no sound. Just as I hung up I heard a loud "plop" sound, which would indicate to me that it was from a call centre. Later I called the number back, only to hear a recorded message telling me that I had called a company called "Digital Solutions", then giving me a menu of buttons to press. Needless to say I didn't press any buttons, just hung up, as I believe it was a scam attempt.
