I think I understand what you mean. I've got Ubuntu 12.10 and by instaling AirDroid, you can access and control your mobile phone from your desktop.
There are two modes:
One using a central site where you conect and.. bla bla, we guys don't care... but works ok!!
The other one is by using mobile phone IP granted by your Wi Fi network, open web broswser on PC and type http://phoneIPaddress:8888 This way your browser will handle the phone... voila
To install AirDroid go to GooglePlay, install it to your android
Run it from your device and copy the IP showed on your
On your desktop web browser, type:
This will open the android screen, that is all.
I recomend using bluetooth headseat for phone calls, this way the PC initiate the call the rest is between the phone and the bluetooth headset. Got one from amazon for less than U$5 and headset cost me around U$30, the more expensive headset were really disappointing.
Hope this helps.
