There was a lot of excitement about the new 47G phone, people were expecting a phone to replace the ancient Aastra model (ZIP 59i). Sadly the phone falls slightly short of the Yealink T48S, lacking the screen size, and touch screen functionality of the Yealink 48G the ZIP 47G still comes across as a solid phone with a modernized look. Zultys does not have a Yealink T48S equivalent yet.
