ADTRAN Announces New IP PBX All-In-One Solution for SMBs

New NetVanta 7060 Lowers Total Cost of Ownership for VoIP Implementations

HUNTSVILLE, Ala.--(April 29, 2008)--ADTRAN, Inc. (NASDAQ: ADTN), a leading
supplier of IP-based networking solutions, today announced that it is expanding its
NetVanta 7000 Series of IP Telephony products with the introduction of the
NetVanta 7060 Modular IP PBX. The NetVanta 7060 is an integrated IP telephony
solution that provides business-class IP PBX features such as voice mail and auto
attendant along with a 24-port Power over Ethernet (PoE) switch in a single compact
platform. This device is ideally suited for small and medium-sized businesses (SMBs)
requiring up to 50 stations per location.

"The NetVanta 7060 comes as the result of requests for a platform that will
economically support the transition to VoIP for those customers choosing to
leverage their existing data network infrastructure," said Tim Saunders, vice
president of product management, ADTRAN Enterprise Networks Division. "This product
builds upon the integrated voice features of our NetVanta 7100 IP Communications
Platform and allows SMBs and distributed enterprise customers to make the
transition to VoIP with a single platform."

This IP PBX offers a wealth of functionality including integrated voice mail (12
hours, eight ports) and a multilevel auto attendant. The NetVanta 7060 also provides
a number of popular key system features such as Shared Line Appearance and Busy Lamp
Field /Direct Station Select. It offers flexible network connectivity with support
for SIP Trunking, T1/PRI and analog connections. The system eliminates the need for
ancillary equipment with an integrated 802.3af 24-port PoE switch supporting 802.1Q
VLANs and 802.1p Class of Service.

Ease of use features are at the center of the design of this platform. The NetVanta
7060 is very easy to use and install, offering a robust Graphical User Interface
(GUI) with getting started menus and wizards that simplify configuration and
management. In addition, graphics-based Voice Quality Monitoring (VQM) is inherent
in the device. This allows network administrators to monitor Mean Opinion Scores
(MOS) and other critical VoIP parameters to quickly and easily identify and correct
Quality of Service (QoS) issues on the voice network.

In addition to the introduction of the NetVanta 7060, ADTRAN also announced the
availability of a number of new features for the NetVanta 7000 Series, including:
SIP Trunking, SIP proxy (eliminating the need for an external SIP ALG device),
system scheduler, the ability to function as a wireless controller, and VQM. The
NetVanta 7060 fully equipped with 24 ADTRAN 706 IP phones lists at approximately
$411 per station. The NetVanta 7060 will begin shipping in June in North America.
ADTRAN has also lowered the price of the NetVanta 7100 IP Communications Platform. A
fully equipped system with 24 ADTRAN IP 706 phones retails for approximately $450
per station.
