Enterprise Systems Corporation deploys Nortel Voice solutions for Hospital

HOUSTON, TEXAS - May, 2005 - Enterprise Systems Corporation announced today that the Company has deployed two Meridian 1 systems with CallPilot for Richards Memorial Hospital in Rockdale, Texas. The systems were installed in the main campus and a satellite location within Rockdale. The systems chosen were both Meridian 1 for voice services and CallPilot for voice messaging. The two facilities are tied together for voice and data via T1. Enterprise worked with Richards Memorial staff for a smooth "forklift" of the Hospital's aging and obsolete Mitel and Harris systems. Emergency services were transitioned smoothly and with minimal interruption.
