“The Longer I use QuestBlue, the more I like this company and how much they care about the customer and doing it right. I have had the opportunity to work with several of the staff & support members, and I will say they are extremely knowledgeable about what they do.”

Christopher Cutshaw

“QuestBlue is the gold standard of VoIP services. We have NEVER been down. We build command vehicles for Emergency Responders, Police, Fire, and Military Agencies. We use QuestBlue because our communication needs are an absolute priority during natural disasters & major events.”

Director of IT Services

“At QuestBlue, they actually answer the phone and I have not had one issue with the process and their portal is better. Since my move, I found the QuestBlue Portal to be easier, faster and all for a lower cost.”
