3.4.2 Dialing Rule
Considering efficiency, it is not acceptable that the gateway reports to the PBX or relevant devices
every time it receives a number. Instead, we hope that the gateway can automatically judge the
received number to see if it meets the set rule, if it is complete and if it is qualified to make
outgoing calls. Therefore, a whole dialing plan, which consists of multiple dialing rules specifying
the auto judging conditions, is required. Each dialing rule has a priority, which is used to restrict
the sequence and avoid conflict.
