This number has been calling me several times in the past few weeks.  Today I answered it and someone with an Indian accent said "hello" and then there was nothing for a few seconds but silence, and then a dial tone.  Wish I could make him stop!

2 calls from this number in the past 2 days.  Answered both of them.  Both call centre employees selling duct cleaning services.

same as everyone else duct cleaning servicE

This number has called me three times as well and never leaves a message.  Damn telemarketers.  When I call the number back, there is never anyone answering the call.
