Overview

Voice Over Internet Protocol (VoIP) is becoming a defacto standard in the industry. With broader use and increasing performance of the Internet, VoIP solutions offer a number of advantages relative to the traditional options like T1, ISDN PRI, leased lines, and Centrex-type services. The cost advantage, infrastructure utilization, and reduced dependence on the telecom carrier are believed to be some of the most significant benefits. Small and midsize organizations now can afford enterprise-grade telecom features once available only to large enterprises. As a result, VoIP solutions rapidly gain popularity in all segments.

Voice Over IP in Use

Our telecom solutions based on the Panasonic KX-TDA Hybrid IP-PBX system are fully VoIP-enabled. This means that we can build cost-effective, easy-to-use interoffice com­munication networks. Using VoIP on the existing wide area network (WAN) or local area network (LAN), our customers can network personnel and office facilities seamlessly both within the company and outside.

IP Gateway Trunks Network several KX-TDA PBXes Centralized voice mail option Save big over ISDN PRI and T1 Greater carrier independence Up to 640 IP Gateway trunks * Voice codecs G.711mu/a, G.729a, G.723.1

The KX-TDA Hybrid IP-PBX system supports one of the widest selection of connectivity options including VoIP. Such a large variety of configuration options translates into the utmost flexibility in tech­nology, features, and cost. Currently, there are two wired IP te­lephones (KX-NT136 and KX-NT265) and the IP Softphone application.

The IP telephones can be installed and supported anywhere within the network and connected home offices. For customers with multiple locations such as regional and branch offices or telecommuters, the IP telephones can eliminate the need for multiple PBXes. The IP telephones support most of the functions of the digital telephones, inc­luding integration with the KX-TVA voice processing system.

VoIP Implementation with Panasonic KX-TDA Series

As an example, a customer with a large cor­porate office and multiple satellite offices can network all locations, telecommuters, and traveling staff by using the KX-TDA se­ries switches. Caller ID information or exten­sion information is passed to the display of the telephone through the network. Emp­loyees on the road can stay connected with the IP Softphone installed in their PCs. A simple 3 to 5 digit numbering plan makes dialing from one office to another as easy as dialing from an extension within the same office. With our VoIP solution based on the Panasonic KX-TDA series, customers reduce their telecommunications costs, gain more independence from the local exchange car­rier, and raise their work force productivity while maintaining a high quality of service, which they demand for mission-critical voice communications.
