Press Release Summary = Vierling launches dual-channel digital GSM gateway for
small- and medium-sized companies

Press Release Body = Ebermannstadt, Germany - July 11, 2007. Vierling, the
international quality and innovation leader in GSM gateways, is now shipping its new
digital GSM gateway Ecotel ISDN2-120 lite worldwide. This dual-channel gateway is
intended primarily for small- and medium-sized companies that want to reduce the
cost of making calls to GSM networks. Ecotel ISDN2 120 lite is based on the proven
Ecotel ISDN2-1x series. With its streamlined hardware and software configuration,
the GSM gateway pays for itself very quickly while ensuring maximum voice quality
and reliability.

Fast payoff for small- and medium-sized companies
"Ecotel ISDN2-120 lite is helping us to bolster our product line for smaller
applications. We now have a GSM gateway that is suitable for companies with 50 or
more employees", noted Anton Glöckner, Director Product Line Mobile Communication at
Vierling. "Ecotel ISDN2-120 lite pays for itself very quickly particularly with the
savings it generates when making calls to mobile radio networks. The hardware and
software configuration does not include components that are required mainly by
larger companies. Ecotel ISDN2-120 lite will allow us to offer the market-leading
technology from the Ecotel ISDN2-1x product line with maximum voice quality,
reliability and PBX compatibility for an attractive price."


All possible connection options
Once it is connected to a company's PBX, Ecotel ISDN2-120 lite takes calls that are
normally routed from the fixed network to mobile radio networks and replaces them
with more cost-effective "in-network" mobile-to-mobile calls. The gateway has two
GSM channels, slots for two SIM cards and advanced routing software. The gateway is
connected to a telephone extension or the central office portal of the PBX via a BRI
interface. The routing can be configured on the PBX or the gateway so that all
standard connection options are available.
