Incoming Calls
In Releases 1.0 and 1.1, incoming calls are routed by line appearance.
Beginning with Release 2.0, incoming calls apply Routing by Dial Plan, a routing
system for incoming calls administered by the Dial Plan Routing Table (see
Table 29).
The Dialed Number Identification System (DNIS) is a service attribute of the
MEGACOM 800 service that routes incoming 800 or 900 calls according to
customer-selected parameters, such as area code, state, or time of call. In
Releases 1.0 and 1.1, DNIS has the restriction of one active call per extension
