If you were considering using simple signal as a VOIP provider, you may want to reconsider. I signed up for their services and soon realized they were as an organized as they were incompetent. Many of the advertised features touted by their sales person Aric Applefield did not even exist. I will literally leave 5 or 6 messages and 10 to 12 emails and still could not get responses from them regarding issues. I finally canceled the service by sending an email explaining why. To do this day they are still billing me even though I canceled the service three months ago. Whatever you do, don't give them your debit card info or look out!
