Testimonials

What Our Customers Say

“QuestBlue is absolutely wonderful. Out of all prior vendors we used for our needs, QB stands out by actually answering phones and emails in real time. Actual people work here, not just bots.”

Sly S.

"I have been using QuestBlue’s SIP Trunks for over two years. I started by transferring a small volume of calls and within a few months had 100% of my SIP Trunks on the Ques Blue network."

Cody I.

"QuestBlue is the best sip trunk provider that I have experience dealing with. Their service team is quick to respond, knowledgeable, and show a desire to solve the problem rather than to meet a quota."
