I use the Peltor Bluetooth headset in our datacenter. Works better than most earplugs for noise attenuation, plus as a cell phone headset it has the noise cancelling microphone. The construction quality is really good, it could be used on a construction site without issues. I highly recommend it. http://www.peltor.se/int/Product.asp?PageNumber=144&ProductCategory_Id=9 &Product_Id=25 Thanks Sameer Khosla Managing Director Neutral Data Centers Corp. 416 682 3434 x5002 (w) 416 682 3435 (f) -----Original Message----- From: Michael J McCafferty [mailto:mike@m5computersecurity.com] Sent: Wednesday, June 17, 2009 9:32 PM To: nanog Subject: Telephones for Noisy Data Centers All, I'd be OK if we were in a facility that was only average in terms of noise, but we are not. I need an exceptional phone for the data center. Something that doesn't transmit the horrible background noise to the other end, and something that is loud without being painful for the user of this phone. Cordless would be very fine, headset is excellent. Ordinary desk phone is OK... but the most important thing is that it works for clear communication. A loud ringer would great too... but if the best phone doesn't have one, I'll get an auxiliary ringer. Does anyone have a phone model that they find to be excellent in a louder than usual data center? Thanks! Mike -- ************************************************************ Michael J.
