The Department of Communications, Information Technology and the Arts (DCITA) went out to tender in March for a new VoIP system for its four locations in Canberra, with the intent of replacing "aged" legacy PABX hardware.
The rollout will include some 950 IP handsets as well as associated software and networking equipment, including softphones.
"The tender was awarded to BTAS, who will be providing the department with a feature rich, scalable and cost effective solution for its IP telephony requirements," a spokesperson for the department told ZDNet Australia this afternoon.
"The IP solution will be fully implemented by October of this year," they added, noting the solution was based on Alcatel hardware.
A spokesperson for BTAS was not immediately available to provide more details about the rollout, nor did DCITA comment further.
According to the integrator's Web site, BTAS is a privately owned Australian company with a client list including QBE, George Patterson, Candle IT&T recruitment, David Jones, Makita and CB Richard Ellis.
