I have had FIVE calls from this number during the past week. Apparently whoever is calling doesn't want to leave a message on the answering machine. This most recent time, I was actually present when the phone rang. The caller ID indicated, "Heritage 2." I picked up the phone and gave a polite hello, and there was no response. I hung up.
Caller ID "HERITAGE 2", Opened the phone circuit but did not say any thing, They did not attempt to say anything, It seems this is a robo call as after a short time the busy signal activates.
