===Former subsidiaries===
CommWorks Corporation was a subsidiary of 3Com Corporation, based in [[Rolling Meadows, Illinois]]. It was sold to [[UTStarcom]] of [[Alameda, California]] in 2003.

CommWorks was formerly the Carrier Network Business unit of 3Com, comprising several acquired companies: U.S. Robotics (Rolling Meadows, Illinois),<ref>{{cite web|url=http://news.cnet.com/2100-1001-274312.html|title=3Com acquires U.S. Robotics|website=news.cnet.com}}</ref> Call Technologies ([[Reston, Virginia]]),<ref>[http://www.highbeam.com/doc/1G1-60306978.html 3Com Corporation Acquires Leading Unified Messaging Vendor, Call Technologies; Company Accelerates Delivery of Carrier-Class, CommWorks Architecture. - Business Wire ]  {{webarchive |url=https://web.archive.org/web/20110516233255/http://www.highbeam.com/doc/1G1-60306978.html |date=May 16, 2011 }}</ref> and LANsource ([[Toronto]], [[Ontario]], [[Canada]]).<ref>{{cite news|url=http://www.findarticles.com/p/articles/mi_m0WUB/is_1999_Dec_27/ai_58393095 |archive-url=https://archive.today/20120629185814/http://www.findarticles.com/p/articles/mi_m0WUB/is_1999_Dec_27/ai_58393095 |url-status=dead |archive-date=2012-06-29 |title=3Com Completes Acquisition of LANSource Technologies, Inc&nbsp;— Company Business and Marketing |year=1999 |work=Edge: Work-Group Computing Report }}</ref> CommWorks was able to use technology from each company to create IP softswitch and IP communications software. U.S. Robotics provided media gateways (the Total Control 1000 product line, formerly used for dial-modem termination) and softswitch technology. Call Technologies provided Unified Messaging software. LANsource provided fax-over-IP software that was integrated with the Unified Messaging platform.

The Carrier Network Business unit of 3Com developed an [[Inter-working function]] technology that became the first and dominant 2G CDMA wireless data gateway product. In partnership with Unwired Planet (now Openwave) and Qualcomm Quicknet connect allowed for 6&nbsp;second connect times versus modems connecting the call in approximately 30 seconds.<ref>{{Cite web |url=https://www.qualcomm.com/news/releases/1997/09/11/3com-corporation-qualcomm-and-unwired-planet-announce-quick-networkconnect |title=Qualcomm Press Center- 3COM Corporation, Qualcomm and Unwired Planet Announce Quick Network Connect Technology: Internet Access For CDMA Networks |access-date=2016-12-10 |archive-date=2024-10-07 |archive-url=https://web.archive.org/web/20241007083609/https://www.qualcomm.com/news/releases/1997/09/3com-corporation-qualcomm-and-unwired-planet-announce-quick-networkconnect |url-status=live }}</ref> This product  was deployed in the United States, [[Japan]],<ref>{{cite web|url=http://www.mobiletechnews.com/info/1999/11/29/000002.html|title= Motorola Provides 64Kbps WAP Access On cdmaOne Networks|publisher=MobileTechNews }}</ref> and Korea covering the 2G CDMA market sample carriers included Sprint.<ref>{{cite news|url=http://findarticles.com/p/articles/mi_m0BFP/is_1999_August_30/ai_55603455 |archive-url=https://archive.today/20120629185830/http://findarticles.com/p/articles/mi_m0BFP/is_1999_August_30/ai_55603455 |url-status=dead |archive-date=2012-06-29 |title=3Com Supplies Critical Wireless Technology for New Sprint Wireless Web Service&nbsp;— Sprint's PCS Wireless Web service&nbsp;— Company Business and Marketing |year=1999 |work=Cambridge Telcom Report }}</ref> It led to follow on products that became core to CommWorks now UTStarcom offerings including the 2.5 and 3G packet data gateway products known as [[Packet Data Serving Node|PDSN]] and Home Agents.

CommWorks/3Com co-developed an H.323-based softswitch with AT&T in 1998 for use in a "transparent trunking" application for AT&T's residential long-distance customers.<ref>[http://www.ilocus.com/ui_dataFiles/news28april06.htm] {{webarchive|url=https://web.archive.org/web/20061216011708/http://www.ilocus.com/ui_dataFiles/news28april06.htm|date=December 16, 2006}}</ref> Long distance telephone calls were redirected from the LEC's ingress CLASS 5 switch to the Total Control 1000 media gateway, where it was converted from TDM to IP and transported across AT&T's WorldNet IP backbone. When it reached the destination, it was passed to the egress LEC's CLASS 5 switch as an untariffed data call.<!-- jargon alert -->

CommWorks modified the gateway and softswitch software to support SIP for MCI/WorldCom's hosted business offering in 2000.<ref>{{cite web|url=http://www.prnewswire.com/cgi-bin/stories.pl?ACCT=104&STORY=/www/story/01-30-2001/0001415835&EDATE=|title=WorldCom Presents Plans for Commercial IP Communications Services|last=WorldCom}}</ref>

Although 3Com sold CommWorks to UTStarcom,<ref>{{cite web|url=http://www.lightreading.com/document.asp?doc_id=29237|title=UTStarcom Cops CommWorks - Light Reading}}</ref> they retained intellectual property rights to the softswitch technology. After modifying the software to enable enterprise PBX features, 3Com released this technology as VCX, the industry's first pure SIP PBX, in 2003.<ref>[http://www.miercom.com/dl.html?fid=bcr-0601&type=print] {{webarchive|url=https://web.archive.org/web/20110716221654/http://www.miercom.com/dl.html?fid=bcr-0601&type=print|date=July 16, 2011}}</ref>
