Extension to Cellular

Extension to Cellular (also known as EC500) is an optional feature that lets you use your cell phone to receive calls placed to your on-campus landline phone number. People calling you no longer need to know your schedule or which phone number to use; they can always dial the same number (your office number) and you'll get the call.

Here's an analogy. Many people have more than one extension of their home phone - an extension in the kitchen, another in the living room. When you get a call, both phones ring, and you can choose where to take the call. Extension to Cellular is like that, where your office phone and your cell phone are the two extensions for calls placed to your office phone.

At this time EC500 is available to faculty and staff with local cell phone service.

In A Nutshell

• When someone calls your campus phone, both your campus phone and your cell phone will ring. You can answer either one.
  
  
• Calls to your cell phone will behave the way they always have. People can call you using your cell phone number. You can make outgoing calls. Nothing changes here.
  
  
• You can use Extension to Cellular with any cell phone with a local (to campus) number. It does not matter what technology or vendor or service provider.
  
  
• You turn the Extension to Cellular feature on and off to meet your needs; you can do this from your office or remotely.
  
  
• Unanswered calls will usually go to AUDIX, the Cornell voice mail service (we say "usually" because there are times when this won't happen. Please see our AUDIX & Voice Mail page for details.)
  
  
• The time you spend on your cell phone as a result of the Extension to Cellular service counts as cell phone minutes. You will incur all charges (including long distance charges) you normally incur for cell phone use.
