I just downloaded Whistle Phone app for my iPad. Unfortunately, I am unable to send or receive any calls. I dial a phone number that I want to dial, but then it shows a red dot on the top. Then I lose connection to all of my internet. My iPad loses all connection, along with my computer for about one minute. I am connected via WiFi to a Netgear router with Bellsouth (AT&T).
On my router, I selected "Disable SIG ALG". The same thing happens. I don't know what to do now.
Correction: When I open up the app I lose ALL connection to the internet, not just when trying to make phone calls.
