By configuring outgoing call rights for a calling number prefix, you can allow calling users whose numbers start with the specified prefix to make outgoing calls after they make trunk-based incoming calls.
Context
Assume that the following requirement must be met: outgoing call right of calling number prefix 0571 is set to local. When the calling party with the number being 0571xxxxxxxx dials the unified gateway main number, and then dials the local outgoing prefix followed by the called number, that is, from incoming to outgoing, the call is allowed by the system. The analyzed calling number is the number that is changed, including the number change that is specified through the config modify trunkgroup command.
