I cant complain as this is already a fantastic handset.
However this may or may not be interesting feedback:
1) 50% of our proposed 525G installations are for the primary purpose of portability within the office
2) The remaining 50% of our proposed 525G installations are simply because of a lack of structured cabling within the office
Based on 2) many users can only use wifi laptops, so why not add a WiFi bridge feature to the ethernet port of the 525G so that they can use their PC plugged into the 525G acting as PC's WiFi client ?!
