What Our Clients Are Saying

“We made the decision to switch from an on-premise telephone solution to a fully hosted solution. G12 offers an experienced team with malleable approach to service and competitive pricing. The G12 team was easy to work with, understood the importance when working with attorneys and the need for little to no downtime during the migration. Service after the installation has been first-rate and timely.”

“It’s the support I get from G12 that makes me always go back to them. I rate a company based on the support you get after the sale. If I have a problem, I simply just make a call to access a level of support that’s unmatched. G12 has been amazing at pinpointing what we needed. They worked with us to ensure we have the right solution and devices. They have certainly gone above and beyond to provide a seamless deployment experience”
Jeff Perry
Director of IT
International Car Wash Group
“Evergreen Hospital has been a traditional PRI shop for a very long time. There are many options when shopping around for a SIP provider, but when we met with G12, it became a very quick and easy decision. The process has been simple, painless, and pleasant. The technology is there, and the price is right. They have the expertise and experience to back their solution.”

Evergreen Health
“With our old system, it often took 2-4 weeks to implement a single new office. With the cloud infrastructure provided by G12, it takes us a fraction of the time. We also enjoy higher capacity, more granular reporting, and significantly better pricing.”

“We’ve been a SIP trunking customer of G12 for 6+ years now, and they consistently outperform on all levels. G12 offers customers technical support that is responsive and invested. G12 alerts have helped detect toll fraud, highlight service-based issues, and maintain a record 99% uptime. Without hesitation, I would recommend G12’s service to any organization considering a transition to SIP.”

“After a comprehensive multi-agency evaluation process, LCOG’s telecom user group unanimously selected G12. They had a proven track record for success and they exceeded our goals for the project. Member agencies benefited from an immediate ROI of 97% savings in carrier costs and have been thrilled with their G12 service since it began on day one. Our members could not have come this far without having G12 as a partner.”
