Call came in on this number, shown on land line w/ Caller ID to be UNAVAILABLE.  Phone rang 2 x's and they hung up w/out leaving a message.  Probably a scammer - don't recognize number.

No CID, no message. Blocked.

same number has called me - ID shows unavailable but number 61--550-8086 shows.
Doesn't seem like they hang up, just stays on the line silent
