Contact center software, since 1996.
InfinityCTI specializes in contact center software solutions — on premise, cloud-based and hybrid — to fit your exact situation. Solutions you expect. Service you deserve.

From a sole proprietorship to a trusted contact center partner.
InfinityCTI, Inc. is a California corporation located in San Diego. It began in 1996 as a sole proprietorship at the encouragement of Avaya Inc., and has worked closely with Avaya and its partners ever since to provide IVR, CTI, CMS and PBX development, support and solutions.
Through the years the business has grown into a team of experienced developers and professionals who support both partner clients and our own customer base. Originally focused on Southern California, our clients today span the United States and Canada.
Our team has a very strong background with Avaya CM, Contact Center Express, Elite Multichannel and custom CTI development — including more than 20 years of experience in the insurance, government, department of defense and healthcare sectors, as well as many other Fortune 500 industries.

Customer retention is our proudest metric.
We at RCL have been using InfinityCTI for our hosted survey platform for over three years and could not have found a better partner. They are responsive, knowledgeable and have always provided best in class service, often bringing solutions beyond our expectations.
InfinityCTI has been a reliable solution for our hosted IVR needs. The team takes the time to listen to our needs, identify potential pitfalls and provide recommendations that allow us to supply our customers with a best in class experience.
InfinityCTI goes above and beyond on every request both big and small. They worked a very big project for Texas Tech School of Medicine against a very aggressive timeline and delivered! I would recommend InfinityCTI to anyone.
