Speaker Phone Problems
Phone works well with one exception. The speakerphone is not full duplex unlike what Cisco advertises. This poorly implemented feature makes this phone unusable as a hands free device. I would not recommend this phone and suggest for with the 504G model which works very well.
Fantastic Phone
I have deployed this phone in as little as 2 minutes. Have plans to deploy these phone frequently in 2011.
