Tellme Networks
A U.S. voice-technology company that built telephone information services and speech-enabled applications.
Last updated August 26, 2026
Overview
Tellme Networks, Inc. was a U.S. communications-technology company founded in 1999 by Mike McCue and Angus Davis. Based in Mountain View, California, it developed telephone-based applications that allowed people to access Internet-derived information and business services through ordinary phone calls. The company emerged during the early voice-portal period, when speech recognition, VoiceXML, and Internet telephony were being combined to create an alternative interface to the web. Tellme’s central proposition was that a telephone could function as a voice-driven information terminal. Its platform supported applications using speech recognition and voice prompts, and it was designed around open standards including VoiceXML, CCXML, and Voice over Internet Protocol. Businesses and developers could use Tellme Studio, a web-based development environment, to create and operate voice-enabled applications on the Tellme Network. This positioned Tellme both as a consumer service provider and as infrastructure for enterprise interactive voice response and automated customer-service systems. In 2000, Tellme launched a public voice portal intended to demonstrate the capabilities of its technology. The service could provide time announcements, weather, brief news and sports information, business searches, stock-market quotations, driving directions, and related directory-assistance functions. Users interacted with the system through spoken commands and telephone keypad input. The service was initially available through the memorable toll-free number 1-800-555-TELL, or 1-800-555-8355. Tellme treated the consumer information line partly as a loss leader: its purpose was to familiarize the public and prospective customers with the company’s voice platform. The company also experimented with features intended to attract callers and demonstrate the reach of its network. Its Phone Booth service offered two free minutes of long-distance calling to a number selected by the caller, although that feature was later discontinued. Seasonal services included a Santa Claus experience introduced around Christmas Eve in 2008 and expanded in 2009 with advance messages describing Santa’s preparations. These products were relatively lightweight compared with Tellme’s enterprise activities, but they illustrated the company’s emphasis on accessible, conversational telephone experiences. Tellme’s network supported services for major organizations, including directory assistance for AT&T and Verizon landline customers, customer-service applications associated with Merrill Lynch, E*TRADE Financial, and American Airlines, and an e-commerce application for Fandango. The company reported that its network processed more than two billion unique calls in 2006, demonstrating substantial scale for a voice-application provider. Microsoft acquired Tellme on March 14, 2007, in a transaction reported at approximately $800 million. The acquisition was completed in late April 2007 and brought Tellme’s speech, voice-portal, and telephony capabilities into Microsoft’s broader technology portfolio. Tellme continued to operate services associated with interactive voice response and telephone information, including the Microsoft-era Bing 411 service. In early 2012, Microsoft divested Tellme’s interactive voice response service and most of its employees to 24/7 Inc. The consumer information service moved away from its former toll-free number and was subsequently known as The Information Line. It was later relaunched as Voice Info in 2019, again with a toll-free number, but that number was deactivated in July 2020. The later service could also be reached through the former Bing 411 number by selecting an appropriate menu option, while AT&T Wireless customers could access it through a carrier short code. Tellme Networks therefore survives primarily as a historical brand and technology lineage within the development of telephone speech applications, rather than as an independent o…
History
Tellme Networks was formed in Mountain View, California, in April 1999 by a founding group led by Mike McCue and Angus Davis. The company entered the market at a time when entrepreneurs were exploring whether telephone networks could provide a practical, spoken interface to Internet content. Rather than requiring a personal computer, Tellme’s proposed voice portals allowed users to call a number, speak requests, and receive information through synthesized or recorded speech. In 2000, Tellme announced a consumer voice portal offering services such as time, weather, news, sports summaries, business searches, stock quotations, driving directions, and directory assistance. The service used speech-recognition software and voice prompts, and was made available through 1-800-555-TELL. Tellme used the consumer product to demonstrate its underlying platform and to build familiarity with voice interaction. A free Phone Booth feature, which supplied two minutes of long-distance calling, was also used initially to attract users before being discontinued. Tellme operated amid a crowded early voice-portal field. Competitors and contemporaries included TelSurf Networks, BeVocal, Hey Anita, and Quack.com, the latter of which was acquired by America Online in 2000. Tellme attracted public attention beyond the technology sector: it appeared in the 2001 documentary Wild at Start and was discussed in a 2000 New Yorker article about recruiting. The company’s network subsequently became more important as a platform for organizations needing automated telephone interactions. Tellme Studio provided web-based tools for constructing VoiceXML applications, while the wider platform supported VoiceXML, CCXML, and VoIP technologies. The company’s services extended from public information to enterprise applications. Tellme-powered systems handled directory assistance for AT&T and Verizon landline customers and supported customer-service functions for organizations including Merrill Lynch, E*TRADE Financial, and American Airlines. Fandango also used the network for e-commerce-related telephone services. Tellme stated that its network processed over two billion unique calls during 2006, reflecting the scale reached before its acquisition. Microsoft announced its purchase of Tellme on March 14, 2007, for approximately $800 million, and the transaction closed in late April. Under Microsoft ownership, Tellme’s voice capabilities remained associated with telephone information and interactive voice response services, including the Microsoft Bing 411 offering. Tellme’s technology represented a route for Microsoft to extend search, information retrieval, and automated services beyond the computer screen. In early 2012, Microsoft sold the interactive voice response business and most of the associated employees to 24/7 Inc. The public information service changed from its original toll-free access number to a regular telephone number and was branded The Information Line. In September 2019, the service was refreshed and renamed Voice Info, with a new toll-free number. That number was deactivated in July 2020, although access routes involving the former Bing 411 number and an AT&T Wireless short code were described for a period. Tellme Networks is consequently best understood as a defunct independent company whose platform and services contributed to the development of commercial speech recognition, voice portals, and automated telephone customer service.
