Service Configuration

Overview

The N2ACD service is built on the N2SVCD framework. Technically it could be considered to consist of a specialised Lua service running within a logic application.

The INAP and SIP protocol support are provided by the N-Squared N2SCP platform and SIP components. ACD has separate service classes for each protocol that can be configured independently or together.

Best Prefix Match

When required to perform two-phase loading, the N2ACD service identifies the target service number for calls by matching the called number with a service number in the N2ACD database. The match can be either a full match or a best prefix match.

When best_prefix_match is false, the target service is identified by matching the full called number with a full service number.
When best_prefix_match is true, the target service is identified by matching the called number’s prefix with a full service number. The longest matching service number will be selected.

Defaults to false.
