Ok, it’s not really a PBX handset. Altigen iFusion SmartStation is a Bluetooth Speakerphone and a charging station with a handset designed to be used with an iPhone. By design it was meant to serve as a charging station and replace your office handset. I have to admit, that a thought of losing my desk phone and replacing it with a SIP softphone app on my iPhone 4S sounded enticing. One device for all needs! Now, I can really take advantage of our hosted PBX. Considering that I need a convenient place to charge my iPhone anyway, why not put it in front of me and use it as a desktop handset?
