Configure a Dial Plan

You can add one or more child dialing contexts to the Corporate and Geographic parent dialing contexts to specify how you want the Oracle Enterprise Communications Broker (Communications Broker) to extrapolate and present universal strings to the routing engine upon ingress, as well as to create target URIs for egress based on these rules.

Configuration includes specifying the applicable:

Prefixes, including:
- Access codes
- Tie line digit sequences
Services, such as 411 and 911 services
Dialing Ranges
Dialing Range exceptions (gaps in dialing ranges)
