Testimonial by Gio Otero
Taking the time to thank you and your team of Engineers at Cornerstone Communications. We had a complete and total voicemail outage and your team of Engineers responded in 30 minutes. We brought our voicemail server to your site and you had it operational in one hour. That is just tremendous customer service! We recommend Cornerstone on all facets of telecommunication services to any existing or future clients. We have been Cornerstone Communications’ client since 1999…that is 18 years of continuity that is unseen in today’s World.
