I have received more than several calls from this number,  The first one that I answered had a foreign sounding, squeaky male sounding voice, trying to sell something, not sure what it was, for I told him I do not accept credit cards, and he said not credit card and mumbled.  I told him that I was not interested and hung up.  
The second time, several days later, some number, same sounding voice and he says please don't hang up and started again.  I 'hardened' my voice and told him politely what do you not understand, I am not interested in what you are trying to offer and I suggested that he go back to whatever hole he crawled out of, and to learn to speak English correctly.
Now when I see the Residence Inn with this telephone number on the caller ID, I tell everyone in the house, do not answer.  I did a google check on the number, which is a California area code number and there is not record of that number being issued.  So, then why, when I hit the return button, did it ring through to have a male voice saying, we appreciate your business, please do not hang up.  I did hang up, and then checked to be sure the dial tone came back up.
