Fax Service, Not Fax Server. Make the Switch Now!

Fax server at its limit. Service contracts that cost a lot and offer little. Terminated or discontinued manufacturer support. Server downtimes that put your business processes at risk. Problems with under or over utilization of capacity and peak loads. IP conversion requires investments in new hardware. There are many reasons why switching from a fax server to fax service makes sense. Make the switch now! It’s definitely worth it.

The result: increased productivity, lower costs. From the very start, and up to 80% over the long-term.

Retarus Fax Services – Advantages at a Glance

Excellent transmission rate

Lower the failure rate of fax transmission by up to 10%. Retarus' never busy technology ensures that multiple fax jobs are never sent to one recipient simultaneously, meaning they can't block each other from being received and you don't need as many resources for manual refaxing.

Intelligent routing

Achieve up to 30% more throughput. Retarus carrier management automatically uses the carrier whose line quality and availability best matches your fax job.


Scalable and flexible

Prevent over and under utilization of capacity. With the Retarus Global Delivery Network you can send 1,000 faxes today and 1,000,000 tomorrow.

Highly available and global

Rely on global availability of reliable transmission. The Retarus Global Delivery Network has its own data centers in Europe, Asia, and the USA, offering maximum international availability. 24/7.
