I want these calls to stop.

Number called our business line.  When answered, no one on the line, no background noise other than a bit of static.  Waited perhaps 30 to 45 seconds, said 'hello' several times, when no one came on the line I hung up.  Suspect it might be an auto-dialer but no idea whose.

no one responded.

that # is actually 222 416 0010
I have call blocked it using Cogeco phone
