Here's what our customers think

IDT Express offers A-Z Voice Termination plans with 3 standard routing and quality options to meet all your needs.


“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!”

Florin Miron CEO/President, KeepCalling

“We can only express our utmost satisfaction for the partnership we have with IDT. Throughout our collaboration, they have consistently demonstrated qualities that make them a trusted and reliable partner, delivering high-quality services.”
