So, we partnered with Five Star Telecom allowing Unitel to sell line and internet services for all the top service providers. No need to call multiple providers, just call Unitel.

When Toshiba announced they were leaving telecom, we used the opportunity to review our industry and selected Sangoma, an Canadian Technology Company that created and manages the world’s most used voice software Asterisk. The open-source software provides an “All Features Included” platform at an ultra-competitive price.

Disaster Relief

We also invested in a Disaster Relief site at a secure facility to provide off-site storage for our IP Communication customers. We include it FREE for all new systems. That’s value for our customers. It’s the reason Unitel Inc. has earned and maintained an A+ rating with the Wisconsin Better Business Bureau.

“Voice over IP Technology that works” Is it magic? NO, it’s Unitel!

A message from our Company President

That’s a tagline I use in our radio commercials and let me explain what it means. We listened to our customers and focused our efforts on meeting their needs and addressing their concerns. They wanted simplicity and real value.

Voice over IP Technology doesn’t have to be complicated; it just has to work. And it’s not magic, it’s years of experience and caring about your customers. That’s Unitel.
