commanding a phone to make a call with zigbee

I'm a beginner level programmer and i wanted to know what i may be able to do to command a phone to make a call. I wanted to use zigbee for the extra range it provides over normal Bluetooth. Eventually later on in the project i would like to incorporate a speaker and microphone into the device that is sending the command to the phone. Any guidance or help with this would be very nice.

Zigbee is not a phone. You would need a cell phone module to make a call.
(somewhat extreme) Example:

Its not that i want the device to make a call its self i want the device to send a signal to the phone which will then initiate the call and then the device will then act like a Bluetooth mic/speaker for a two way conversation. I assumed you could use zigbee as the means for communication between the device and the phone.

I assumed you could use zigbee as the means for communication between the device and the phone.

Why did you assume that? Zigbee has its own protocol, how is the phone supposed to know that? Maybe you could write something on the phone but I suspect it is buried in the phone's operating system.

then the device will then act like a Bluetooth mic/speaker for a two way conversation.

If this is at all possible, which I doubt, then it is quite an advanced project and something I have not seen being done before. Are you up to doing original advanced projects on your own yet?

Im not really up to doing advanced projects on my own yet im still pretty new to this stuff. I guess i assumed it because i know you can use a smartphone to do things like control quad copters and various devices i didn't think that this type of communication would be much different, but then again I am new to this.

Yes that is one problem beginners have these days. Because they see something in a consumer product they expect it is something that is easy to do. There is a vast range in the processing power of different processors out there and while you can do a great deal with the Arduino there are limits.
