The above dial plan realizes that calls from GSM network, Asterisk will
connect it to SIP phone 500 which has registered previously. When
internal phone dials 100, Asterisk will connect to 10000 through the first
channel and similar functions with the last three calls. After edition,
please run "asterisk -r" again, and then execute "reload" in the CLI. All
above complete successfully, you are able to make calls.
