Called Sunday, 10/19/14, 12:36 am. Caller ID showed "ALA" with this number. My phone answered by Sentry robo call blocker which gives message that we do not accept calls from telemarketers and to remove our number from "their call list". Also informs them if they want to leave a message, press 0. No message left. Known no one in DC area.
They called with "ALA" & knowing it was a telemarketer, I whispere "hello, hello." Guy on the other end said "hello?!" And I whispered back "hello" and the hung up.
