A friend of mine snapped this photo of my all time favorite Nortel telephone, the rugged and reliable M2616 Aries II. This phone appears to be in good shape with no yellowing. Many hospitals and large institutions still use these phones, but many others have been sent to the trash in favor of Cisco. Avaya and E-Metrotel still maintain and support these phones on their respective platforms. Avaya supports it on the Nortel legacy Meridian1 and CS1000 while E-Metrotel supports the set on all of their UCx platforms.
No reason to throw them away just yet. I personally feel these phones still look modern today.
