Ratings and Reviews


No support

I have had an iPhone since it first came out and have always been impressed with how the developers share the same view of ease of use and set up as the Apple name implies. Until this app. Avaya obviously doesn't get the idea that if the consumer has an iPhone they simply do not wish to learn how to build a watch to tell time. No support.....took forever to get someone on the line other than an automated attendant. I wouldn't recommend this app....if you have Avaya in your office forward you calls to your iPhone thru the website and avoid this hassle at all costs.

Technologist at heart

Indispensible! A must for all EC500 users.

I have been a long time user of Avaya's Extension to Cellular feature (EC500). It has saved my company thousands of dollars (if not tens of thousands). This Avaya one-X Mobile Lite application is clear, simple, and extremely effective. I HIGHLY recommend Avaya's EC500 feature and this application.


Good App

Does exactly what it's billed to do. The best part is you don't have to convince your IT folks to deploy a one-X Mobile server. :-)

There are some quirks related to how the UI functions after placing calls but as I understand it these are due to the way the latest iPhone OS functions.
