Mashable has a slide show of 10 docks that are used to turn your iPhone into a DeskPhone.
Here are a couple that I found interesting:
The iDock Phone and Speaker $40
The iRetroPhone with SyncCharger $100
See the rest at: http://mashable.com/2012/09/02/iphone-docks-desk-phone/#851051-Native-Union-Curve-Bluetooth-iDock
BTW – Many of these will work with other smart phones as well.
