“When we decided to switch to Cloud Based Communications, INTERMEDIA was one of a number of highly rated systems. We went with Intermedia because it is supported by Envision with whom we have worked for over 20 years. They provided excellent support for our previous phone system. They have long term employees who are knowledgeable and easy to work with. We much prefer to work with a local company that understands our needs. 

Envision’s staff took time to understood our staff’s busy schedule and worked around it to minimize any disruption to our operations.

Intermedia’s Desktop app makes it easier for team members to communicate with each other by seeing who is available, send messages and place calls. The mobile app is a time saver since team members can be reached wherever they are with one call instead of trying their office extension and, when there is no answer, then calling their cell phone.  Being able to call patients from our cell phones and having the main office number display instead of our personal phone number has been very useful.  We are currently working with Salesforce to integrate one of their healthcare CRM solutions with out Intermedia system. When a study volunteer calls, their information will automatically come up on the desktop which should be a real time saver for our staff. We will also be able to send texts and documents to study participants via this application.”

Captain Andy’s Sailing Adventures

Since 1980, Capt Andy’s has been providing epic tours to Na Pali on Kauai, one of the most beautiful coastlines in the world.  The reservations group receives over 200 calls per day and was limited by a poorly performing hosted VoIP telephone system.  Envision was selected to install a Digium Switchvox IP PBX with a new Cisco data network.  The Digium delivers exceptional call center functionality and quality.


“Thank you so much for everything you have done for us and for your patience in the sales process answering our questions about the system’s capabilities.  We truly love our new Digium phone system!”

-Trisha Lorenzo, Director Marketing and Sales

I Kitagawa & Company, Ltd.

I. Kitagawa and Company, Limited has been in the Car Business on Hawaii Island since 1915, operating the Kamaaina Motors, Kamaaina Nissan and the Kona Auto Center dealerships.
The Company has been selling Chrysler Products since 1936 making it the oldest Car Dealership in Hawaii and one of the oldest Chrysler Dealers in the United States. Kamaaina Motors has strong roots as a homegrown family owned business that is still run by the same family that started it over 100 years ago, currently run by the founder’s great grandson.
Envision was selected to replace problematic telephone systems at the dealerships in order to improve call quality and enhance the customer service experience. The Mitel Mivoice Office PBX combines reliability, efficiency, easy to use features and mobility to direct calls to staff anywhere on each property.


“Envision did a great job installing our new Mitel VoIP PBX systems at our dealerships and quickly resolved any problems that came up after the cutovers.  We also leveraged Envision to upgrade our Cisco data network.  We would happily recommend Envision and their services”

-Brian Kitagawa, President

PBS Hawai’i

PBS Hawai’i

“Envision came highly recommended and provided PBS Hawai’i with a complete solution for our new facility. The Digium system gives us flexibility to move phones easily to accommodate our staff as well as support our volunteer phone banks during live call-in public affairs programs. We’re very happy with our decision.”

-Leslie Wilcox President and CEO of PBS Hawai’i

PBS Hawai’i selected Envision to install the Digium Switchvox IP PBX and Cat6 Data Cable in their beautiful two-story, energy-efficient building on the corner of Nimitz Hwy and Sand Island Access Road. The installation was coordinated with the IT vendor and Contractor.

The design allowed a single cabling infrastructure to support both the data network and voice applications provided by the Digium PBX.

Hawaii Prince Hotel Waikiki

As part of a $57 million renovation of the Hawaii Prince Hotel Waikiki, Envision was contracted to upgrade existing legacy infrastructure with Category 6 and Fiber backbone cabling. The new cabling will support IP-TV, future IP phones and wireless access in each room. Envision’s engineering approach found ways to reuse existing pathways which resulted in cost savings for the hotel. Over 9000 feet of fiber and 223,000 feet of Cat6 cabling were run.


“Envision has been nothing but a joy to work with, their professionalism and expertise is second to none. They were instrumental in identifying the requirements and technical aspects of the cabling infrastructure throughout the hotel property to facilitate our IP Televisions and state of the art WIFI network. Prince Resorts Hawaii has also contracted Envision for our telephone maintenance at all three of our island properties and corporate offices. We continue to enjoy professional and expeditious service response.”

-Ryan Doi, Corporate Director Information Systems

Hanalei Bay Resort

Hanalei Bay Resort is a premier timeshare vacation destination located on the North Shore of Kauai; consisting of 16 buildings housing roughly 240 residential condominium units. An aging copper infrastructure was replaced with a new, more modern outside plant cable design that incorporated terminal pedestals to replace problematic buried cable and splice cases. Envision designed and deployed the new cable distribution system for their in-house (PBX) telephone system by reclaiming and refurbishing salvageable assets to reduce cost, while expand capacity by adding and redistributing additional cable pairs were capacity was needed. Termination components were selected specifically to address a harsh corrosive tropic coastal environment.


“Envision did a fantastic job creating and installing our phone system cable renovation here at Hanalei Bay Resort.” – Greg Veal, General Manager
