McCormack Networks  has provided technology services to businesses and organizations in our area for over a century. Below is a sampling of testimonials from companies that trust us to meet their technology needs.

Ozark Border Electric Cooperative recently purchased an Avaya IP Office Phone System from McCormack Networks. There were several complicating factors involved in the transition: additional extensions, implementation of a PRI, reconfigured call groups, etc. In addition, the system had to interface with our network and, specifically, with our after-hours IVR (which we had updated just months before). I am happy to say McCormack Networks’ staff did an excellent job with the transition. They were in constant contact with us, our IT company and our phone carrier and were very thorough in determining the sequence of events which needed to take place. The transition was very smooth and we are extremely pleased with the product we purchased as well as the service we received. We would highly recommend McCormack Networks to anyone contemplating a phone system purchase.

SCMCAA is a not for profit community action agency operating programs in a seven county area. We have purchased phone systems from McCormack Networks for our administrative office and also several for our outreach/head start centers during the past 15+ years. We have found McCormack Networks and their staff very courteous and professional at all times. They have always been available and helpful in providing follow up assistance with any problems we might incur (even if these problems are not related to the equipment but, issues with local bell companies and/or as a result of staff changes).

Thank you and your crew for the responsible, dedicated and timely work you performed for us. It was apparent that your crew was knowledgeable, professional and willing to go the “extra mile” to make it work. I think the most astounding fact is how non-invasive your crew was around our staff and the almost immediate return to phone service you and your crew provided.

We are very pleased with your performance and with our system.

I wanted to take a moment to thank you and your staff for the great service that is always provided to us. Your prompt attention to issues is one of the many reasons we continue to rely on McCormack Networks for our entire telephone and intercom system. I also appreciated the willingness of your company to work with us on e-rate funded projects to insure the paperwork is completed properly to enable the school district to fully realize the financial benefit of the e-rate program.

Thanks for all you and your staff do to help keep our communications technology up to date and working properly. The ability to communicate is a key to success.

I have been very pleased with the business telephone system we obtained from McCormack Networks/Ellington Telephone Company. The quality is excellent, their personnel knowledgeable and friendly. When we needed to expand the system it was done smoothly and efficiently. I would highly recommend McCormack Networks.
