On the 19th and 20th of May at the financial heart of Europe, in the German city of Frankfurt, Panasonic SIP Phones, in partnership with Broadsoft who specialise in IP voice software, introduced the new generation of Panasonic SIP Terminals at the Panasonic European SIP Convention 2011, aimed to manage the global communications of thousands of users. These devices operate as an open standard, developed for the transmission of multimedia applications over IP networks.

They are true data processing centers as much as they are Panasonic SIP Phones, however, they are prepared to work just as well in the home as in business environments. Panasonic has prepared the launch of more than about ten SIP Phones all with their own design, unique technology and environmentally friendly ethos. Likewise, it brings to the forefront their new audio systems that produce high definition signals for all of their new range of telephones, which permits the conversations be clearer than those found in previous calls.

The purpose of the meeting was to show some of the solutions and features that will emerge in the market throughout the year. The two series, Panasonic UT and the Panasonic TGP, incorporate large LCD screens with a simple interface, Wideband HD Sound, certification for use with Digium Asterisk and Broadsoft for BroadWorks and an easy configuration which also allows the use of a wide range of accessories.

The Panasonic KX-UT series has six terminals; the Panasonic KX-UT113, Panasonic KX-UT123, Panasonic KX-UT133 and Panasonic KX-UT136 come as desktop solutions that cover the range from standard up to professional office. On the whole, the Panasonic KX-UT248 and Panasonic KX-UT670 will be responsible for the executive level and office work respectively. Both work with Android and are designed for the most demanding environments.

The company also showed other phones like the NS1000, which was launched in December and acts as a switch that can operate up to 1,000 users. The phone will be complemented with the full range SIP IP Platform from Panasonic. In short, a set of devices ready to work in the cloud, a requirement that is becoming indispensable.

Carlos Osuna, European Product & Marketing Manager for Panasonic SIP Phones, said the company expects a good reception from the products in Europe, “We expect to reach 20 million Euros, it sounds ambitious, but we can obtain it.” For the distribution of their Panasonic catalogue they will rely on the Partner Connect Program, launched in April at the European level.
