Yeastar S-Series VoIP PBX Overview


We could reduce the number of phones


“We had spoken to a few larger telecom companies about our install but came away from those meetings feeling a little less than warm and fuzzy. John Adams really got to know us and our business. In fact, our Executive Director told me, ‘we’re going with AdamsComm, Inc, even if they are more expensive.’ The fact that we could reduce the number of phones based on an app AdamsComm installed made this decision a slam-dunk.”

Chad Leavell, Director of IT, Community Systems, Inc.

They will make it happen


“As part of our renovation, AdamsComm installed a new VOIP system and rewired the entire network—voice and data. When you’re working with AdamsComm, you’re working with people who know their business, who up-to-date technology-wise and incredibly responsive. Give them a time frame and they will make sure it happens.”

–Doris Christiani, controller, Lawrence Lynch, Corporation

They blew us away with their level of service


“Our company has added two new offices over the past three years and our small phone system was not powerful enough to support our growing business. AdamsComm, Inc. provided a top notch product for a solution. But where they blew us away was with their level of service. AdamsComm, Inc. supported us through every phase of the project.”

– Mike Duffy, program director, TNT Energy

Transition to the new system was seamless


““The reason we chose AdamsComm, Inc. to install the system at our new office had nothing to do with telephones. They took the time to get to know us and understand our business. They didn’t try to sell us a Cadillac when we were looking for an efficient, mid-size sedan. And the transition to the new system was seamless.”

    Chatham Police Department

    “AdamsComm, Inc. has handled our department’s voice and data services for over nine years.  John and his team have given us highly personalized attention and have provided us with outstanding customer service.  John designed and implemented our first system; then provided unbiased professional guidance on the maintenance and improvements for it.  When our system needed to be upgraded, John recognized our agency’s budget and technology limitations, and designed and installed a successful new system.

    We are a 24 hours a day, 365 days a year organization.  John and his staff are always very easy to reach and quick to respond and his company’s work ethic makes AdamsComm one of the best vendors we have ever worked with.

    We would strongly recommend John and AdamsComm and hope that we can continue to work with them in the future.”

    Deputy Chief Mike Anderson
