Aylus Networks Launches Video Calling Offering at GSMA Mobile World Congress Show

Enables Mobile Operators and OTT Service Providers to Take Advantage of the Market Opportunity from a Projected 150 Billion Minutes of Video Calling Per Year within 5 Years

BARCELONA, Spain, February 17, 2011 - Aylus Networks(TM) (www.aylus.com), the leading enabler of rich
communication (www.aylus.com/solutions.html) services utilizing video,
announced today at the Mobile World Congress Show Aylus Video Calling
(www.aylus.com/service-applications.html) offering, which enables
mobile operators and OTT (www.aylus.com/service-enablement.html)
service providers to offer video calling as an extension of voice calls.
Today, more and more smartphones and other mobile devices come with
front-facing cameras designed to enable video chatting or calling. However,
video calling services are still limited to calls between particular devices
and communities of interest on certain networks and they offer no quality of
service or user experience guarantees, issues that are limiting video calling
uptake. Aylus Video Calling is changing all of that.

"We estimate that within five years 15% of all mobile voice calls will
add video to their calls, representing over 150 billion minutes of video
calling per year," said Mark Edwards, CEO of Aylus Networks. "As total
revenues for the mobile industry surpass the $1 trillion mark in 2011, with
$750 billion in voice calling, this is a huge revenue opportunity for the
industry. Voice revenues are under pressure and declining due to competition
and regulation. The industry needs to innovate and enrich communication
sessions by adding new value-added services such as video calling, multi-way
video calling, fixed-to-mobile video calling, video voice mail, and by
connecting diverse communities of interest across different networks."

Aylus Video Calling enables users to start with a voice (circuit-switched
or VoIP) call-between any two video-capable mobile devices, regardless of
manufacturer or model-and transform that call into a two-way video session.
Premium video calling capabilities enable video calls between multiple
parties, from one social networking community to another, and to devices that
may not be running the same video calling client or application. The Aylus
Media Platform ensures that video conversations are optimized and enhanced
based on both the network traffic at any given moment and the devices
involved in the session. Furthermore, traditional supplementary voice
services work as before. This delivers a much more integrated user experience
than other video calling offerings, which require you to launch an
application and require the receiving party to have the same application
installed and running.

Aylus Networks provides the only integrated media platform that enables
rich communications, service interconnect, RAN optimization & QoE management.
Aylus provides a real-time advanced media switch and processing platform that
enables service providers and OTT providers to enhance, deliver and monetize
communication sessions. Aylus provides seamless continuity for communications
between the voice and data network. This allows them to add video, drop video
and revert back to the voice network while seamlessly supporting all existing
supplementary services for voice and to add premium video calling services.
Aylus can connect calls across different communities of interest on the same
network and on different networks.

"Aylus Video Calling builds on the operators' existing reliable, secure,
functional voice calling infrastructure (circuit-switched or VoIP) that
people know and understand how to use," Edwards added. "As mobile services
continue to evolve from offline/fixed networks to real-time/mobile networks,
Aylus Video Calling enables mobile operators to capture new revenues from
carrier branded video service offerings while optimizing network bandwidth
utilization. It also helps OTT service providers to monetize their services
with premium offerings and deliver managed, stable and secure services that
can scale for enterprise customers."
