Network Call Redirection (NCR) provides a call routing method between sites on a public network or a Virtual Private Network (VPN) reducing trunking costs. Cost reductions are particularly valuable in enterprises or multisite call center environments where trunk costs are high.

Public Switch Telephony Networks (PSTNs) or VPNs manage call redirection when an incoming call arrives at Communication Manager that has the NCR feature enabled. As a result, trunks that the server normally retains to accomplish a necessary trunk-to-trunk transfer are released after call redirection takes place.

Cost reductions associated with reduced trunk use can be significant, particularly when you implement Avaya virtual routing features such as Best Service Routing (BSR) with Expected Wait Time (EWT). You can achieve cost savings by using fewer trunks to handle the same number of incoming or outgoing calls after implementing NCR within the local Communication Manager.
