Business Editors/High-Tech Writers

LOS ANGELES--(BUSINESS WIRE)--April 13, 2004

aeroTelesis, Inc. (OTCBB:AOTS) aeroTelesis has officially opened an office in El Salvador. This office is the first of a series for Central America in the rolling out of aeroTelesis' proprietary VoIP network.

Representing aeroTelesis in the deployment of its technology is newly hired Vasquez and Bonilla Telecommunicaciones S.A. DE C.V. Vasquez and Bonilla, made up of Mr. Hector Vasquez and Mr. Alfonso Bonilla, will act as the in country representative for aeroTelesis, negotiating new opportunities for aeroTelesis to penetrate the market in Central America with its VoIP capabilities.

The relationships that Vasquez and Bonilla have developed and maintained with local operators in El Salvador will position aeroTelesis to use its Ultra Spectral Modulation (USM) technology. aeroTelesis values both Vasquez and Bonilla as highly motivated, experienced and knowledgeable executives to assist with the development and integration of USM into an existing network.

Vasquez and Bonilla have already met with local operators to implement VoIP, and their responses have been positive. Vasquez, whose resume includes key positions with VB Telecommunicaciones and PointRedtechnologies Inc., stated, "We met with local operators, and they are very receptive and highly motivated in proceeding to the next step for a live demonstration which has been scheduled."

Dr. Jagan Narayanan, Chairman and CEO of aeroTelesis, remarked, "Central America is an important emerging VoIP market for us. Considering that Central America is a large market for all international calls for the United States, we see it as being potentially one of the larger markets for aeroTelesis for the deployment of USM."
