Iphone 6 Plus with IOS8.1 Keeps restarting when making outgoing calls via yosemite desktop

Hi,

I'm using a 2013 MBA upgraded to the latest Yosemite OS X. My iPhone 6+ is running IOS 8.1.

I had set up the sms relay and cellular calls connection. Most run as advertised. However, I do observe a peculiar occurrence when making outgoing calls from the desktop which I will like to check if anyone is facing a similar situation and if there is a solution to it.

When making outgoing calls from the desktop, the iPhone keeps restarting. I keep seeing the white screen with the black apple logo. Once it goes into the main screen, it restarted again and again and again for the duration of the call. During the whole time, the call is uninterrupted and clear.

Is anyone else facing this situation? I look around and seems like i'm the only one. While it does not affect the function, it means I cannot use the phone while making an outgoing call on yosemite because its constantly restarting.
