Weird Bluetooth behaviour with new iPhone 6s

[Umiamz]

Just got a new iPhone 6s Plus and paired it with the Discover Navigation system (which I assume is the same as the Composition Media as far as Bluetooth is concerned). Every time I get in the car and the phone connects, the hands-free attempts to make a call to my own mobile number. Every time. When I look at the iPhone it's not actually making a call, but the hands-free is stuck in the call - the red hangup button doesn't do anything. The only way round it is to make a call to another number and immediately hang up. It works normally after that.

I don't know whether it's the hardware in the iPhone 6s or iOS 9 that is responsible. My old iPhone 5s had no issues. Anybody else had any problems?

Thanks...

Have you updated to the new iOS 9.0.1 update? It fixes some odd bluetooth bugs like this.

Yes, but I've discovered what the problem is - it's the new "Hey Siri" feature. The phone listens for you to say those words and activates Siri. I turned that off and it all works fine now

Apparently you get the same odd bluetooth behaviour with Android's "OK Google" and Microsoft's Cortana on some of their phones.
