Call outgoing doesn’t work
No sound
Perhaps I'm doing something wrong, though it's hard to know what this would be, since the application is so simple. But whenever I "dial" a number using Operator on my iPhone, the dial tone persists for a while on the land-line phone, and then I get a busy signal, even when I know the phone I'm calling is not busy. This happens every time and with every number. I've tried adjusting the iPhone volume, and I've adjusted both the dialing speed and the gap between tones in the settings for the application. Nothing works. The iPhonso website provides no support of any kind. (Also, why does the screenshot show the user holding the earpiece of the iPhone next to the microphone of the land-line phone, when the tones play through the speakers on the other end of the iPhone?)
It is just a great idea, being able to dial from your iphone into another phone.
