They just keep calling. They seem to have a range of number numbers in the 202-315-53xx range. I have added them all to my Ooma blacklist page and that has helped. I have avoided adding all the 53xx range, but it is getting close. When I question them as to who they are, they keep saying the Humane Society of the United States. When told we are not interested and to remove our name, they say they will and then they call from a different number. This whole range of numbers should be considered suspect.

A recorded message said I had a call then sounded like it switched me over then nobody came to the phone after a few seconds.
