I've been trying to bring this up but I keep forgetting. Whenever I use Siri to call someone, i.e., "Call my brother", it will find it and then start calling. However, as soon as the number is dialed, Siri/iPhone disconnects/hangs/ends up the phone. This is the first time it has happened. I've had previous iPhones, all the way to the 2G model and never this problem. Well, I mean iPhones that voice recognition. And yes, I have tried with different iPhone 4S and still the same. So, it's not my car. My car is capable of receiving the artist name/song/album when I BT stream my audio, so I'm pretty sure it's not an older BT. My car is a 2010 Toyota Prius. Anyone here have the same problem? I've learned to deal with it, since I can just easily go to all calls and redial it myself since it would be bumped all the way to the top. But, I'd rather not do that when driving. Thanks.
