The Internet is still in its infancy. We can see an important development in the form of Voice over IP (VOIP) that is showing up both in private IP networks and on the public Internet. This development will have profound consequences for the traditional telephony industry. For one thing, VOIP is simply part of a richer fabric of Internet-enabled communication, not an end in itself. Moreover, it dictates a very different pricing structure for such services, considering that Internet services are basically flat price services that vary only with the capacity of the access circuit. Already many carriers have adjusted to this new reality with the introduction of fixed-priced consumer service and advantage services. More innovation will come from the major carriers in the years to come. Internet services and applications will in time re-invent the technology itself. The Best is yet to come!

SIP Phones

• Pingtel — Pingtel xpressa phones are feature rich, open to add-on features, easy to use and stylish. In addition to dozens of standard features, add-on applications include an LDAP phone book, integration with Outlook, ACT! and WebEx, and custom ring tones. An open interface makes new feature creation easy. All features are made easy by hints that display on the LCD. Colors include Latte (white), Sambuca (gray), Indigo (blue), Mocha (brown), and Mango (yellow-orange).
• Cisco — The Cisco IP Phone series is a standards-based communication appliance. Cisco IP phones interoperate with IP telephony systems based on Cisco CallManager technology, H.323, or Session Initiated Protocol (SIP) and, in the future, Media Gateway Control Protocol (MGCP), with system-initiated software updates. This multi-protocol capability is an industry first and provides investment protection and migration capability. Each Cisco IP Telephone provides Toll-quality audio and doesn't require a companion PC. Because it is an IP-based telephone, it can be installed anywhere on a corporate local or wide area IP network.

SIP Phone Adapters

• Mediatrix — The Mediatrix devices are adaptors that connect conventional telephones or G3 fax machines to a Local Area Network (LAN). They access an Intranet or the Internet to permit high-quality, full-duplex, audio/fax communications over IP Packet Networks.

Quality of Service

• Sitara Networks — Sitara is providing its traffic management product line known as QoSWorks. The technology in these products enables comprehensive QoS management of both voice and data traffic. QoSWorks is the industry's first QoS platform to integrate all of the QoS tools that network managers need to prioritize all traffic at the edge of the network.

SIP-Enabled Firewalls

• Ingate — Ingate Firewalls prevent unauthorized access to and from enterprise networks while allowing SIP-based communications such as presence, instant messaging, audio/video conferencing and VoIP. All messages entering and leaving the network are routed through a firewall, which examines each packet and blocks those not explicitly authorized to pass.
• Intertex — The IX66 Internet Gate from Intertex represents a new generation of advanced, highly functional and compact broadband access products. The firewall has the unique feature of handling IP Telephony and other applications conforming to the SIP standard. Also the Intertex IX66 is an ideal product for the small office space.

Gateways

• CommWorks — CommWorks provides the Total Control® 1000 Media Gateway and CommWorks® 4007 Signaling Gateway to bridge MCI’s IP Communications between an Internet protocol (IP) network and Public Switched Telephone Network (PSTN). The gateways integrate easily into a variety of network environments, supporting wireline, wireless and other access technologies.
• Cisco — Cisco is providing the 2600 and 3600 series routers for use at the customer premises. The Cisco routers have the versatility to support data, voice, video, and hybrid dial access applications, and high-speed connectivity.
