answered call no one there, called back no answer!

answered call no one there, called back no answer!

I just got the call too.  Without anyone saying anything,

The person I spoke to said her name was Lisa Phillips and claimed to be callin from the office of Khsshamanjit Singh from Hanover Research.  I've received several calls from people claiming the same company.  They are trying to get to my boss, but can't get past me.  I wish they would give up and stop wasting my time.

I am getting repeated calls from this number, and no message left. The number being called is a cell number for my consulting firm. It sounds from reading above this may be a cold call to businesses.
