The Challenge: Unpredictable VoIP Network Conditions

Fax communication remains a critical function for many organizations, even in today’s era of advanced digital communication. While the T.38 protocol was developed to enable fax transmission over IP networks, it has inherent limitations in reliability. These challenges did not exist when traditional fax machines were connected to PSTN lines, as they relied on stable and predictable transmission environments—conditions often absent in VoIP scenarios.

In VoIP applications, the unpredictability and variability of network conditions pose significant obstacles for fax data transmission. Fax communication, which relies on the precise exchange of data, is especially susceptible to packet loss, jitter, and latency commonly found in such environments. These issues can lead to incomplete or failed fax transmissions, undermining the reliability required for business-critical communications.

Our Solution: Leveraging POTS Media SBC

To address these challenges, Flyingvoice introduced a POTS Media SBC to enhance data reliability from the endpoint to the cloud. Unlike traditional T.38 implementations, our approach focuses on leveraging T.30 raw fax data for improved performance. Here’s how our solution works:

1. T.30 Data Transmission: The endpoint device captures raw fax data in T.30 format, the protocol used by traditional fax machines over PSTN.

2. POTS Media SBC as a Reliability Layer: The T.30 data is transmitted from the endpoint to the POTS Media SBC. Acting as an intermediary, the POTS Media SBC ensures robust handling of the data, compensating for packet loss and network variability. This step significantly enhances the reliability of the fax data before it proceeds further.

The Benefits of POTS Media SBC

Integrating POTS Media SBC into your communication infrastructure delivers:

1. Enhanced Fax Reliability: Minimized disruptions caused by network impairments, ensuring successful transmissions even in challenging environments.

2. Compatibility with VoIP Systems: Seamless operation with modern VoIP platforms, preserving your existing investments.

In summary, while T.38 has served as a foundational protocol for fax over IP, its limitations in challenging network environments necessitate an alternative strategy. By employing a POTS Media SBC to handle T.30 raw data and leveraging G.711 for platform integration, Flyingvoice provides a robust and reliable solution for fax communication in the age of VoIP. This innovative approach ensures that even in the most adverse network conditions, fax transmissions can be completed with minimal disruption.
