Exhibit 99.7

                   Avocent Acquires Sonic Mobility;
Acquisition Adds Wireless Network Administration from and of PDAs and
                             Smartphones

    HUNTSVILLE, Ala.--(BUSINESS WIRE)--Sept. 1, 2004--Avocent
Corporation (Nasdaq:AVCT) today announced that it acquired Sonic
Mobility Inc., a privately-held company located in Calgary, Canada.
The agreement provides for a total cash purchase price of $8 million
plus the assumption of liabilities and payment of certain transaction
costs.
    "The Sonic Mobility acquisition adds a suite of software products
for secure wireless systems administration and mobile device
management on multiple platforms, including BlackBerry, Pocket PC, and
Palm platforms," stated John R. Cooper, president and chief executive
officer of Avocent Corporation. "Avocent currently provides management
and access solutions for fixed IT assets and believes the addition of
Sonic Mobility's proprietary products will expand our markets to
include solutions for the fast-growing market for mobile IT assets."
    Sonic Mobility's products include sonicadmin, software for mobile
devices that allows management of network and data center
infrastructure, sonicsecureweb, security software for intranet and
extranet resource access from mobile handheld devices, and
sonicsentry, a software solution for managing mobile devices centrally
by IT administrators.
    The sonicadmin software uses a real-time secure proxy model to
perform many routine server administrative functions from a mobile
device. For example, the administrator can reboot a server,
unlock/change passwords, restart services not functioning properly,
view event logs, move files and send messages to logged-in users.
Microsoft has licensed sonicadmin to be the software that drives the
Windows 2003 Mobile Admin Pack.
    Sonic Mobility recently introduced sonicsentry, a software product
for the remote control and administration of PDAs and smart phones
that connect to a computer network. The new product adds a new level
of network security for mobile devices. IT administrators can monitor
all mobile devices for current status, apply passwords to unprotected
devices and manage mobile user groups, as well as a number of other
functions. For mobile devices that are lost or stolen, sonicsentry
allows the IT administrator to centrally control and wipe out
sensitive data. The product is ideally suited for networks that
utilize cellular PDAs and smartphones to support staff in the field.
Planned enhancements include over-the-air provisioning and
configuration of devices, ideal applications for carriers that support
a large number of mobile devices.
    Sonic Mobility has strategic relationships with Palm, Microsoft,
RIM, NetIQ, and RSA. Sonic Mobility has over 300 customers in 14
countries, including Lockheed Martin, FedEx, Principal Financial, the
U.S. State Department and the U.S. Department of Justice.
    Sonic Mobility CEO, Derek Ball, will join Avocent and will become
Avocent's Director of Business Development for Mobile Solutions. He
will be joined by Dayton Foster, Sonic Mobility's VP of Engineering,
and the software development team. In connection with the acquisition,
ten individuals who became non-executive officer employees of Avocent
following the acquisition will be awarded a total of 40,000 employment
inducement stock option grants by Avocent. These grants will have an
exercise price equal to the closing share price today, September 1,
2004, and will vest over a period of four years under terms that are
substantially similar to the 2003 Avocent Corporation Stock Option
Plan that was approved by Avocent's shareholders in 2003.
    "We have already begun to integrate Sonic Mobility's mobile device
solutions into future Avocent products," continued Mr. Cooper. "The
combination of sonicadmin with our DSView and DSAdmin products will
extend our management solutions to mobile devices. We are also excited
about the potential of the continued development of sonicsentry and
the large market opportunities for remote wireless management of
mobile devices. We believe this is a very attractive market for
Avocent and look forward to developing it with Derek Ball, Dayton
Foster and the Sonic Mobility team."
    The acquisition is not expected to have a material effect on
Avocent's third quarter results, except for a to-be-determined charge
for acquired in-process research and development.
