What They’re Saying

Customer Testimonials

Called QuestBlue to discuss moving my service. Wasn’t looking forward to it based on past experiences with other vendors in this field but needed to do something because of the downward spiral of my current vendor. 

They put me in touch with one of their techs and he explained the fee structure and was very thorough in answering my questions. Next thing I know he is helping me with the entire process of moving my DID’s and getting me set up so once the porting is done I will be live and ready to go! 

Start to finish they took the stress out of the process. QuestBlue is the gem in the jewelry box! Thanks!”

We have been hosting our PBX with QuestBlue for over 3 years now. They are the best and most affordable providers in the business. Talk about blazing fast response times from support, near 100% network up time and the best prices I have seen anywhere for usage, LD, DID, PBX hosting etc.

Looking for a better way to manage your VOIP setup? Look no further than QuestBlue.

“The longer I use QuestBlue and get to know the employees and staff, including the owner, 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 and support people and I will say they are extremely knowledgeable about what they do. As an IT professional for well over 20 years, I have a real issue with tech support personnel that treat me like I just read “IT for Dummies”. The staff has been incredibly helpful and they always speak to me at my level. They are awesome. I highly recommend this company and this group of highly knowledgeable professionals. I can’t say enough good things about them.”
