            eXpeTel Communications Chooses DSET Gateways and Services

- -------------------------------------------------------------------------------


Bridgewater, NJ - January 15 - (Nasdaq: DSET) - DSET Corporation announced today
that eXpeTel Communications will deploy DSET electronic-bonding gateways to
automate the pre-order process and the ordering of local phone lines for new
customers. One of the fastest growing regional competitive telecommunications
providers in the Southeastern U.S., eXpeTel will use the DSET ezPreOrder and
ezLocal gateways to interconnect with trading partners that include BellSouth
and Qwest Communications.

The DSET gateways were acquired by eXpeTel in December 2001 under DSET's gateway
rental plan. The ezLocal gateway will also interface with billing software from
SCBI to reduce order-entry keystrokes by some 80 percent, giving eXpeTel
virtually total flow-through order processing.

eXpeTel, which entered the CLEC business in early 2001, is rapidly evolving into
a full-service provider of local telephone, long-distance, and data services for
homes and businesses. The DSET gateways will facilitate the provisioning of
voice and data lines for eXpeTel's rapidly growing customer base.

DSET will also provide eXpeTel with maintenance and change-management services
relating to the gateways. The change-management services will ensure
continuously efficient interconnection between eXpeTel and its trading partners
should a trading partner change any unique data requirement affecting
interconnection.

"Our primary reasons for choosing DSET's gateways included their range of
features and ease of integration with other key OSSs," said Wade Spooner,
president and chief executive officer of eXpeTel. "Automating the pre-order and
ordering processes with these products will help us provide the quality of
service essential for winning and keeping customers. The integration of DSET
software with our billing system will also provide the current and future
back-office capacity we need to sustain rapid growth and maintain significant
operational efficiencies."

"Although there have been dramatic changes in the telecommunications market over
the past year, some competitive service providers are now looking at the
possibility of implementing electronic-bonding gateways that will improve their
chances of taking

                                                                     Page 1 of 3



business away from the large incumbents, such as BellSouth or Qwest," said Bill
McHale, DSET's president, chief executive officer, and chairman of the board.
"We are very pleased that eXpeTel embraced the value that our solution provides
as they streamline their provisioning processes."
