I've had my 202 installed for about a week now. I have only a single phone attached at the Phone-1 port, and I'm using Anveo for SIP and E911 service on SP1, and GoogleTalk on SP2. I was just now sitting at my desk when a call came in form CallerID 100. When I picked up the receiver there was silence (no dial tone). What is the most likely source of a random call from "100" ??
Thanks
