Voice Recognition Issue on '13 Yaris SE

[s3la]

Hello all,

I am the proud new owner of a 2013 Yaris SE. I've run across an issue with voice recognition, in regards to placing phone calls.

My device is paired and all contacts have been transferred.
I can use my device to manually place a call but I haven't been successful with the "Hold "Call" until you hear a beep then say "Call/Dial John Doe"" tactic.
I've thoroughly reviewed both manuals for the head unit and the car and have not been able to find where I might be going wrong.

I don't know if I'm doing something wrong or if it is a fault in the car.

Any advice on how to successfully place a call, using voice recognition, would be greatly appreciated.
