We chose Agility to supply our new Avaya phone system, in no small part because of the strong referral provided by our IT group. This decision was a good one. All deadlines were met or completed prior to requirement, and communication among all parties was very detailed and appropriate. The install coincided with a cutover from a previous phone service provider to a new one, including a migration from T1 to dedicated fiber. This proved to be no problem for Agility.
3 months post install, I can still contact my Solutions Consultant and be sure to get a same day response.
I have dealt with several phone vendors and manufacturers over my career, and can say without a doubt that Agility has a plan in place that places a premium on customer service.
