Merge cca18c7b7e into 3b58ebc5f3

We observed that the new Poly phones (formerly known as Polycom) were not getting sent a SIP UPDATE in certain circumstances (example: retrieving a parked call, and therefore, Caller ID would not show the parked caller). I renamed Polycom to Poly which will catch all Poly AND Polycom UA's. I also added Acrobits, and Ringotel to extend such functionality to those UA's. There were also other minor compatibility issues with the new Poly phones which have been resolved with tweaking the UA recognition on the code.
