Here's another type -- a disconnected cell phone number being used by a scam artist by spoofing the disconnected number of 7736838180. When you dial it using Fire RTC, it rings endlessly. However, when you dial with another source, you hear the SIT with cellular operator message that the number is disconnected.
This is a horrendous waste of time and resources to be dialing disconnected, non-working numbers that FireRTC leads the unsuspecting user to believe are valid, working, ringing numbers.
Buddy, why is this? Please reply. I've left three requests over the last month to no avail. This problem greatly impacts the viability of the business model and the usefulness of this product.
