Dial Plan Overview

The wide application of VoIP has resulted in more and more dialing plans. While
service flexibility is enhanced and customer requirements are satisfied, reasonable,
operable number management becomes increasingly important. A dial plan can
help voice gateways to manage numbers in a unified way and create a
management policy for all numbers, making number management more
convenient and reasonable. The dial plan process on the calling side differs from
that on the called side. The following discusses these two dial plan processes
respectively.
