McFarland, WI - July 2004 - The 1Call Division of AMTELCO is pleased to announce the successful
integration of the 1Call Infinity system to the LVM eCentaurus™ nurse triage software package. This
streamlined integration gives healthcare organizations another powerful way to simplify enterprise-
wide communications for faster, more efficient, and more accurate call handling.

With the Infinity and eCentaurus integration, operators answer calls, gather information from callers,
and screen them for nurses. If the operator determines that the caller needs a callback from a
nurse, the operator simply saves the message in a special Infinity account. The message is then
automatically dispatched to the LVM eCentaurus software package, which presents calls to nurses in
the queue, based on the priority of the call.

When the nurse receives the call, information about the call, including the callback number, is
displayed. The nurse uses the eCentaurus screen, with the Infinity Windows® Operator Interface
Engine, to dial, connect, place calls on hold, page, and patch calls to doctors.

To complete the call, the nurse presses a button on the eCentaurus screen. The Infinity system
stores all of the information about the call, including the callout history, which can be archived and
reviewed at any time for quality assurance and billing purposes. If desired, incoming and outgoing
calls can also be automatically recorded using the 1Call Voice Logger module.
