Outgoing Calling Rules
An outgoing calling rule pairs an extension pattern with a trunk used to
dial the pattern. This allows different patterns to be dialed through
different trunks (e.g. "local" 7-digit dials through an analog line but "long
distance" 10-digit dials through a low-cost SIP trunk). You can optionally
set a failover trunk to use when the primary trunk fails. The Outgoing
Calling Rules give you the ability to use basic pattern matching to
differentiate outbound calls and route them accordingly. The tab displays
each outgoing calling rule established and the service providers assigned.

Note: Outbound Calling Rules manages only individual outgoing
call rules. See the Dial Plans section to associate multiple outgoing
calling rules to be used for User outbound dialing.

the rule will match against, the trunk used to complete the call, and the
failover trunk to be used. of call. Several default calling rules will be
available when you initially set up your Asterisk Appliance 50. Click on
