Linksys Announces SIP-Based IP PBX, Desktop Phones, and Gateway For Internet Telephony Service Providers

IP PBX and Phones Enable Service Providers to Deploy Residential and Small Business Phone Systems with Big Business Features and Functionality

IRVINE, Calif. – January 5, 2006 – Linksys®, a Division of Cisco Systems, Inc., the recognized leading provider of voice, wireless and networking hardware for the consumer, Small Office/Home Office (SOHO) and small business markets, today announced a new line of SIP-based telephony products for Internet Telephony Service Providers (ITSPs) targeting large residential, SOHO and very small business customers. The new line of IP communication solutions includes an IP PBX/Key system, a wide range of IP desktop phones and an Analog Gateway for connection to the Public Switched Telephone Network. Used together with an ITSP voice service, they provide a complete IP telephony system for up to 16 users.
According to AMI research, there are more than 35 million small businesses world wide. 56% of these businesses have 1 to 4 users, and another 11.8% have 5 to 19 users. The new Linksys IP telephony products target this market segment. ITSPs focusing on the higher-end of the residential market, or the lower end of small business market can deploy services on this platform to help customers save money by using the Internet to make telephone calls.

“With the new Linksys SIP-based IP communication offerings, ITSPs can offer residential and small businesses a voice service with many of the features found in large business voice IP networks, such as multi-line service, music on hold, auto attendant, and more at a more affordable price,” said Jan Fandrianto, vice president of voice engineering at Linksys. “The new IP PBX and IP phones bundled with a service provider offering will make the deployment of voice networks easy to install and simple to use at a price small businesses can afford.”

This new solution will complement the recently announced Linksys One VoIP phone system. Linksys One is an ideal solution for small business with 5-100 users needing a complete communications solution that addresses voice, video, and applications. The LVS series was developed to address the residential and very small business of 1-4 users that may grow to 16.

The Linksys SIP-Based IP Products include:

Linksys IP PBX: SPA9000
The Linksys IP PBX lies at the heart of the telephony solution, delivering advanced, multi-line features commonly found in enterprise telephone networks. With the Auto Attendant feature, small businesses with up to 16 users can customize their voice network to direct calls to the right person or department and program the system to allow on and off business hour greetings. A promotional message can be created to greet or provide information to callers placed on hold, or pipe in the music of choice. The system also allows users to park calls, fax over the Internet and use the intercom for paging. There are over one hundred telephony features built-in.

    Well, you can say what you like about Linksys. . . They rush their products to market, they don’t support them.
    The products don’t work as advertised. . . And, They don’t fix their mistakes.

    Take the wpb54G. . . It doesn’t work properly with WEP 64bit Open encryption. . . You can take encryption off. . .
    or you can screw around with it, and KLUGE it into working. . .

    Frankly, at this late stage, I expect something to work “magically”. . . I don’t want to have to screw with technology
    that everybody and his brother has working properly.

    Linksys is a horrible company. Don’t buy their products unless you can’t avoid it.
