Received a call from this telephone number. No message was left. Anonymous callback reached a quick "blurp", silence followed by someone saying "Hello".

Past occurrences reveal an association with Canadian pharmacies. Not sure if this is valid here, but, I wanted to throw it in.

Calls and doesn't leave message-caller ID says Worcester Ma

We got a call from this number today at 9:17 am. The caller ID was WORCESTER MA, and it was blocked by our call blocker. This must be a new number for these lowlifes. Due to other such calls, our call blocker blocks all calls with this caller ID. I highly recommend such a device to avoid these nuisances.

This number was not blocked in my block list. What Ken (above) is saying that his blocking also includes ID names, so does mine (a PC software / modem version), if the name ID is anything else than "WORCESTER MA" (like "WORCESTER" or "MA WORCESTER") it will not be block. Problem there are tens-of-thousands  combinations of towns and state, but of course if it is a town-and-state ID it is almost guaranteed a SPAM call. When will all this stop?

Call from  508-453-0154.  No message.
