We know what we’re doing because we’ve been doing it for a long time. And we’re good at it, too. As a team, we bring over eighty years of industry-acquired expertise to the table. VoiP System Engineers, Developers, Consultants, and Technical support specialists. At Calliotel, you’ll find it all, done well.


Why deal with multiple companies, when you can work with one? At Calliotel, we cover everything from consulting and engineering to wholesale call routing and VoIP support. Whatever a VoIP business needs, we can provide.


We are skilled at what we do and we really want is to learn from you. For every project, we make it our mission to work with you, to grow with you, and to assist you so that the end product isn’t just what you get, it’s exactly what you wanted.


Because we believe in doing it right the first time. The more we understand the requirements of the task ahead of us, the better equipped we will be to work out all of the custom-designed details in the final needs. While many companies will list for you the different platforms and vendors they develop in–and yes, we do it all–it’s not technology that guarantees successful results. What matters most is listening to clients, knowing how to efficiently develop within a budget, and ultimately custom designing solutions that are both flawless and intuitive. Our experienced team of consultants and developers will design what you need, implement it, test it, and even maintain it. From building VoIP systems to modifying source codes to creating phone applications, we’ll make sure that what we do works for you.


At Calliotel, we offer our clients the very best in service, expertise, and support. Passionate about our work and dedicated to producing innovative, customized solutions for every business we collaborate with, our results speak for themselves.

For every project, with every client, we are challenged to see things differently, through a renewed perspective, ensuring that our body of work is always original, inspired, and exceptional.

We are builders. Whatever your business needs, we can construct it, from the ground up. But first we need a blueprint. Calliotel works with clients to discover precisely what they are looking to achieve and how software can best meet those needs.
