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 (OECB) 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)
