Avaya EC500 Mode D'Emploi

Issue 3  August 2002

Welcome to being connected wherever you are! Instead of being tied to your desk 
waiting for a call, the Avaya™ EC500 Extension to Cellular (EC500) solution 
offers you the freedom to work anywhere, anytime, using your cell phone. With 
EC500, calls to your office number are extended to your cell phone, allowing you 
to receive work-related calls wherever you are and whenever you need to. EC500 
even provides office caller ID, so you know who’s calling before you answer.

EC500 is ideal for anyone who conducts business on the go — salespeople, field 
service personnel, real estate agents, physicians, attorneys, engineers, 
operations staff, consultants, brokers and other mobile professionals. Even 
telecommuters working in their home offices can use EC500 to make the 
transition from office to home transparent to callers.

With EC500, incoming calls to your office number reach you on the road, at 
another location, or even walking around the workplace. This “one number 
reachability” means you can respond immediately to urgent business matters. 
And when you can’t respond, your voice mail picks up your messages. 

EC500 works with any type of wireless/cellular service. And, you control your 
availability by connecting or disconnecting to EC500 (we call it “enabling” and 
“disabling”) as needed. Whether connected to EC500 or not, your cell phone still 
operates as it always has. You still receive personal calls on your cell phone, 
because personal calls come in through your standard cellular number and 
service provider. 

This guide focuses on the Dual Setup user (a cell or remote phone with two 
extensions for call waiting) because it is the most common EC500 setup. If you 
have another type of EC500 setup, consult the Appendix for additional user 
information.
