Dial Rules
Path: Telephony -> Outbound Control -> Trunks
On the IPPBX system you can setup different dial rules, for users to dial numbers in different format/pattern and
cause the IPPBX system to call out through different trunk lines. For example, users dial the numbers with a prefix
9 to call out through the CO lines (land lines). Or dial the numbers with a prefix 00 to call out through the VoIP
lines (SIP trunks).

 First of all in the Dial Rule Name blank specify a name to identify this dial rule.
 In the Time Conditions dropdown list, you may select a time condition for this dial rule, so this dial rule will
only be available to be used at business hours.
