Number calls at least three times a day if I answer nothing but background noise.  If machine answers no message is left.

Answering machine picked up this number twice yesterday, once so far today. Yesterday caller ID gave the name of the city where I live (none of the three listed as Location below this form). Today it said Out of Area. The message was only the sounds of a call center. This number has called in the past; think it may be Cancer Support Services seeking donations
