Chapter 16: Out Call Routing Configuration
AltiWare ACC 5.1 Administration Manual 233
Dialing pattern configuration tips
• If a dialing pattern has multiple routes assigned to it, the system will try to use the
first route configured to process the call that has this dialing pattern. If the first route
is busy or not in service, the system will use the second route, and so on.
• If a dialing pattern requires the system to add or remove digits, a route with digit
manipulation configuration needs to be set up correctly. This means that you may
need to have the same group of trunks belong to different routes. Each route may
have a different digit manipulation rule.
• If you are using dialing pattern to restrict outgoing calls, you need to be aware of
the following system implementations:
– The system first checks to see if the number is blocked for this extension (a setting
in the Extension Configuration window, Restriction tab).
– The system then checks the System Configuration Call Restriction tab settings
to see if this number is blocked by the system.
– The system then checks the Dialing Pattern configuration, and if a specific
number or pattern is not blocked, the system will dial the number through a
proper route.
In other words, if extension and system call restrictions are not blocking a number
or pattern, you can use Out Call Routing to build restriction rules to block numbers
or patterns.
