“Before interconnecting IDT Express, it was a challenge finding a carrier with reliable routing.  Our customers experienced call quality and stability issues. We tried the Platinum route offered by IDT Express and haven’t looked back in 4 years. The quality level has exceeded our expectations.”

Ioannis Vamvakaris, CEO/Co-Founder, VoiceLand

“We started with IDT a few years ago and our
relationship has been growing steadily ever
since. We primarily use their Platinum and
Gold routes and the quality has been
consistently meeting our expectations. Our
account manager has also been very proactive
and helpful throughout!”
