Reliably send and receive faxes from anywhere

Take the guesswork out of whether or not your fax is going to reach its final destination or end up in the ether. Flowroute understands the T-38 protocol and how it should be implemented to securely and reliably transmit documents from anywhere.


Experience and knowledge that ensures your success.

Deep T-38 expertise

Flowroute's support engineers are not only fully trained in all aspects of our network and a broad range of UC, PBX and call center system technologies, they also have a deep understanding of the T-38 protocol and how to implement it successfully.

Award-winning support

Flowroute has an award-winning, world-class team of Customer Support Engineers. Eastern Management Group (EMG) has repeatedly recognized Flowroute as the number one SIP Trunking provider in customer satisfaction. Additionally, the group has achieved an NPS score of +59 for the last six months - a strong indication that customers would recommend Flowroute to others.

Predictable porting process

Flowroute’s proprietary porting process, carrier status, and relationships ensures faster completion of port orders. Typically, customer port orders complete in 2 weeks, and are delivered in a scheduled two-hour porting window.

  • “Flowroute support is the best in the market and I have dealt with over 150 SIP providers in the last five years.”

  • “Flowroute products and service are excellent. As someone who is just getting started with VoIP trunking, I got the same good support that I would expect for people who are doing more volume."
