Nortel, which is similar in many ways to Avaya, has two main levels of systems and deployment as well as support and integration for its legacy PABX user base. The first solution is suited to the SME market with the BCM 200 and 400 series, supporting up to 150 users and starting at less than AU$10,000. The enterprise-level equipment is the CSE1000 which can scale from 200 to 15,000 users.
An innovative and vendor-independent overlay for any VoIP system is the Nortel MCS5100, which provides advanced multimedia support and capabilities to VoIP networks, and is fully SIP compatible.
Nortel is targeting sites with 100 or more users as well as its existing installed base of PABX and key system users. Some of the high profile users of Nortel VoIP systems include, ANZ, JB Hi-Fi, and the University of Ballarat.
