Dial plan
Dial plan configuration provides diversified number management functions. Dial plan configuration involves number substitution and number application.
Number substitution means applying the number substitution rules to the calling and called numbers to substitute them. Number substitution includes number substitution rules and binding of number substitution rules.
Number application means matching numbers, controlling the sending of numbers, and selecting voice entities according to match templates. Number application includes number match policy, rules in the match order for voice entity selection, maximum-call-connection set, number sending mode, and call authority control.
The dial plan configuration directly affects the selection of voice entity and the final call connection. The dial plan configuration involves global configuration, voice subscriber line configuration, and voice entity configuration. You can select one or more configurations for a dial plan. The global configuration acts on calls of the whole VoIP gateway, the voice entity configuration on those of the voice entity, and the voice subscriber line configuration on those of the voice subscriber line.
