Patent Issued for System and Method for Processing Telephony Sessions

July 3, 2014



By a News Reporter-Staff News Editor at Computer Weekly News -- A patent by the inventors Lawson, Jeffrey G. (San Francisco, CA); Wolthuis, John (San Francisco, CA); Cooke, Evan (San Francisco, CA), filed on January 16, 2013, was published online on June 17, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8755376 is assigned to Twilio, Inc. (San Francisco, CA).

The following quote was obtained by the news editors from the background information supplied by the inventors: "In the last decade, legislation and the advent of Voice over Internet Protocol (VOIP) have revolutionized the communication industry with new technologies, business models, and service providers. Software and commodity hardware now provide an alternative to expensive carrier equipment. One can implement extensible call switching and voice application logic in Open source software applications, such as Asterisk and FreeSwitch. These new application stacks, however, usher in new complexities and challenges, requiring new skill sets to deploy, develop, and maintain. Deploying telephony services requires knowledge of voice networking and codecs, hardware or services to bridge servers to the public phone infrastructure, capital investment in hardware, and ongoing collocation of that hardware. These burdens are a mere prerequisite to developing the actual application, which requires developers to train in new languages, tools, and development environments. Even telephony applications that currently try to leverage a model more similar to web-development such as Voice Extensible Markup Language (VoiceXML), require the dedication to learn a new language and understand telephony interaction. Ongoing operation and maintenance of these services requires teams to adopt new analysis tools, performance metrics, and debugging methodologies. Developing even the simplest of voice services (such as a so-called 'phone tree') requires significant upfront and ongoing investment in specialized infrastructure, skills, and operations. Thus, there is a need in the telephony field to create a new and useful system and method for processing telephony sessions. This invention provides such a new and useful system and method."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "The method of the preferred embodiment for processing telephony sessions include the steps of communicating with an application server using an application layer protocol, processing telephony instructions with a call router, and creating call router resources accessible through an Application Programming Interface (API). The method and system of the preferred embodiments enables web developers to use their existing skills and tools with the esoteric world of telephony, making telephony application development as easy as web programming. The method and system use the familiar web site visitor model to interact with a web developer's application, with each step of the phone call analogous to a traditional page view. Within this model, developers reuse their existing tools and techniques, including familiar concepts such as HTTP redirects, accessing resources through an API, cookies, and mime-type responses to construct complex telephony applications. The method of processing telephony instructions and creating call router resources accessible through an API (a call router API) cooperatively function to enable a stateless and simple telephony language with more call router resources and information provided through the call router (preferably a REST API as is familiar to many web developers). In one embodiment, the telephony instructions set may have fewer than dozen verbs, simplifying the language so that developers can quickly learn and implement telephony applications, while the call router API compliments the simple telephony instructions to enable complex telephony applications."
