Default Dial Rules
The CMA system has three default dial rules. With these defaults, the system
can route most calls except those requiring an external DNS lookup.
• Internal IP - This dial rule allows the system to identify the incoming dial
string as an IP addresses and routes the call out of the region. By default,
this dial rule applies to all sites.
• Alias - This dial rule allows the system to identify the incoming dial string
as belonging to the local directory and routes the call to the local device or
service, as required.
• DNS Name - This dial rule allows the system to identify the incoming dial
string as a DNS name and block the call.
Parts of a Dial Rule
A dial rule consists of a pattern type paired with a routing action. When the
dialed string uses a pattern that matches the pattern type, the associated rule
is applied.
Pattern Types
A pattern type tells the CMA system how to find a match for the dial string.
The following table shows the available pattern types.
Note
Do not delete the default dial rules or the CMA system will not be able to route calls
correctly. You can disable a dial rule by editing it and clearing the Enabled check
box for the rule.
