Dialogic Brooktrout SR140 Fax Software

Brookout SR140

Overview

Dialogic® Brooktrout® SR140 Fax Software, a host-based Fax over IP (FoIP) engine, brings the power of industry-leading Dialogic® Brooktrout® fax hardware products to software-based solutions.

Using Brooktrout SR140 enables Dialogic’s partners to focus on increasing the value of their document management and business process automation solutions while maintaining regulatory compliance with directives such as HIPAA and Sarbanes Oxley. A software-based solution also can make it easier to move toward virtualized or cloud-based architectures, and create highly available and scalable platforms or services.

Two License Options Available

Brooktrout SR140 is scalable from two (2) to hundreds of ports, depending upon the FoIP transport method,  application, and server environment. Channels can be added as needed by purchasing and installing additional software license keys up to the maximum supported. Two license versions are available:

  • 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. This license is referred to as the "full SR140 license" below.

  • SR140-L - provides a more basic feature set for lower density fax processing environments

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 software partners around the world. 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-based 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.

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. In addition, SR140 optionally supports the ITU-T T.38 Recommendation for Internet Aware Fax (IAF), which defines a real-time method for sending faxes directly between two FoIP endpoints over an all-IP network. During Dialogic-conducted testing between two locations over a SIP trunk, a 15-page document that took ten (10) minutes to transmit using T.38 V.17 took only six (6) seconds using T.38 IAF.

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

Enabling FoIP When T.38 Is Not Supported

G.711 fax pass-through is supported by the full 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.

Support for RFC 6913

Starting with Dialogic® Brooktrout® SDK 6.7, SR140 supports IETF RFC 6913 for Indicating Fax over IP Capability in the Session Initiation Protocol (SIP). This feature allows service providers to selectively route FoIP calls over specific networks and improve the reliability of global FoIP faxing.

Fax Security

Starting with Brooktrout SDK 6.8, SR140 optionally supports both SIP over TLS and SRTP. SIP over TLS secures the SIP signaling exchange, while SRTP secures the RTP fax media stream when using G.711 mode.  Changes are not required to an existing SR140-based applications in order to implement SIP over TLS and SRTP.

Common Fax API for Both TDM and IP

Brooktrout SR140 supports the Dialogic® Brooktrout® Bfv API, the same API used by all Brooktrout fax products. Developers can choose to write one application to the Bfv API and deploy it on both TDM and IP equipment. This dual-network support also allows developers who wish to sell into both TDM and IP accounts to use either Dialogic® Brooktrout® TR1034 Fax Boards or Brooktrout SR140 as the fax technology in their solutions.

Key Features

T.38 IP fax protocol implementation encapsulates Dialogic® Brooktrout® T.30 fax data stream

Leverages 20 years of experience with the T.30 stack, which Dialogic enhances to maintain interoperability with new fax equipment and to enable a high degree of reliability and efficient fax processing

G.711 fax pass-through

Can support fax on an IP network when a gateway or IP network operator does not support T.38, broadening the range of possible installations

V.34 transmission speeds for both T.38 and G.711

Can process faxes at twice the speed of V.17 fax products, reducing long distance toll costs

T.38 Internet Aware Fax (IAF) over UDP

 

Supports ITU-T T.38 Recommendation defining a real-time method for sending faxes directly between two FoIP endpoints over an all-IP network, eliminating TDM, G.711, and modem derived speed limitations

SIP over TLS and SRTP fax security

Provides signaling and media encryption for secure fax communication; supports FIPS Object Module, which is required for JITC certification

API support for collection of network quality metrics

Useful in determining suitability of underlying fax transport, such as an IP network, for providing fax service

Voice play and record and DTMF detection and generation

Allows fax integration into IVR and call center systems for improved customer satisfaction

Server virtualization support

Enables the deployment of fax server applications on virtual machines with leading server virtualization software, which increases data center efficiency and provides failover for mission-critical fax applications
