Dialogic Brooktrout SR140 Network Fax Software

Dialogic® Brooktrout® SR140 Fax Software is a host-based Fax over IP (FoIP) engine that leverages existing field-proven Dialogic® Brooktrout® fax technology to deliver the high levels of performance, reliability, and scalability of Dialogic® Brooktrout® fax hardware products.

In combination with solutions from Dialogic’s software partners, Brooktrout SR140 allows organizations to deploy fax servers and fax server applications for document management, business process automation, and regulatory compliance with Sarbanes Oxley, HIPAA, and Basel II.

Brooktrout SR140 is scalable from 2 to 120 channels in a single server (or virtual machine). Channels can be added as needed by purchasing and installing additional software license keys up to the maximum supported.

SR140 provides a rich set of FoIP features and functions suitable for high-speed, high-density fax production environments in both enterprise data centers and hosted service provider networks. Disaster recovery licenses are available for creating a backup system, which can be used during an interruption in service.


Brooktrout SR140 has been certified in SIP, H.323, and MGCP environments and has been tested and certified with IP-PBXs and VoIP gateways from leading vendors, including Cisco, Avaya, and Alcatel-Lucent.

Time-Tested, Industry-Leading Fax

Dialogic delivers time-tested industry-leading fax technology, offering a broad range of fax and FoIP products, which are supported by more than 50 software partners and approved for use in more than 40 countries (as of 2010). Brooktrout fax technology has been deployed for more than 20 years.

FoIP solutions built using Brooktrout SR140 can send and receive IP faxes at up to 33.6 kbps, based on the V.34 fax standard. Not only can Brooktrout SR140 process fax at twice the speed of 14.4 kbps fax boards, but it also supports V.8 fast handshaking and advanced compression, which can cut call setup and session-management time by one-third. A document that can be faxed in one minute with a 14.4 kbps intelligent fax board can be sent in less than 30 seconds with an application using Brooktrout SR140. This can translate into significant savings on long distance toll charges.

Brooktrout SR140 can deliver highly reliable FoIP by using the T.38 fax protocol to send real-time fax messages over IP networks. Because the T.38 protocol retains the standard T.30 fax data stream, it can be used with legacy T.30-based devices and with newer T.38 solutions. With over 20 years of experience, the Dialogic® Brooktrout® T.30 implementation can lay claim to being the most thoroughly field-tested offering compared to those of all other fax technology vendors.

Dialogic has refined its T.30 implementation for numerous T.30 variants, which helps make fax processing reliable, saving customers time and money. The T.38 stack has also undergone significant interoperability testing with other IP vendors. This successfully tested interoperability provides flexibility and reliability when the SR140 is deployed into IP networks.

Enabling FoIP When T.38 Is Not Supported

G.711 fax pass-through is supported by the SR140 license version. While more susceptible to possible IP network issues, such as packet loss, jitter and latency, G.711 fax pass-through provides an option for enabling FoIP when T.38 is not supported.
