Avaya one-X [EOL] Reviews Summary
Author infoRatingReview Summary
Manager, Telecommunications at Gyrus ACMI - Olympus4.0I find one-X Communicator and Mobile excellent for remote work, greatly improving work/life balance as users can answer desk phones anywhere. My main complaint is one-X Mobile's inconvenient call-back before dialing out.
