Stroke rehab - phone use

I'm breaking one of my rules in this situation. Rule - Always go for recovery, do not compensate. At my new workplace we have a standard phone on the desk. It should be so simple to put the phone in my left hand and hold it to my ear, leaving my right hand for writing stuff down or surfing the internet while in a phone meeting. I tried this a couple of times, it takes me 3 minutes to get the phone in my hand, prop my elbow on the desk and I still have to hold everything with my right hand. My wrist curls down, my lats pull my arm to my side with extreme persistence, my ear does not stay on the receiver and I can't get everything back to usefulness without using the right hand.  Without spasticity to contend with this would be a simple exercise in repetitive movements. So I'm going to get a headphone set that allows me hands-free operation. The problem is that its a Cisco IP phone that requires a headset that has a normal phone jack connection, Best Buy and Officemax don't carry them, supposedly Staples does. Staples is $120, I'm buying it from Amazon for 19.95 As an ADL there must be a therapy protocol out there someplace for recovering phone abilities(not compensating/cheating like me). Cell phones are impossible to use in my left hand, I end up punching all the buttons and I can't keep the phone to my ear. Which is why I compensated and got a bluetooth.
