Dallas, Texas - July 24, 2002 - DTVN Holdings, Inc., (OTC BB: DTVN), a
nationwide provider of packet-switched information services through its wholly
owned subsidiary DataVoN, Inc., today announced that a change of control has
taken place. Transcom Communications, Inc. has been, or will be, issued
sufficient common stock to give it a 51% ownership interest in DTVN.

In connection with this significant change in ownership, the Company announced
that Scott Birdwell has become Chairman of DTVN's Board of Directors and CEO of
DTVN. Britt Birdwell and Jeff Becker have been been appointed to the positions

DTVN's new Chairman and CEO, Scott Birdwell, said, "We are very excited about
our new roles at DTVN and DataVoN. DTVN and DataVoN have been facing significant
financial challenges that had to be addressed. Last week, Transcom agreed to
assist the Company in that endeavor in exchange for a controlling interest in
the Company. We are hopeful that with our financial strategies, substantial
telecommunications experience and the combined expertise of the management team
we will be able to meet those and other challenges going forward. On a positive
note, although we have only been here a short time, we are very impressed with
power of the DataVoN network and the prospects for future growth."
