TeleGuard Incoming Call 

Testing incoming call and chat in TeleGuard app. TeleGuard is one of the most private messenger in the world. No phone number is required. You just pick a nickname and hit Register. Then, you add contacts using the unique 9 symbol ID or QR code. It's that simple!
Nobody from your contacts or those who have your phone number in their contacts will know that you are using TeleGuard until you decide to communicate by sharing your ID or QR code.
P.S. Nice ringtone and notification sounds :)
