Polycom CMA System Operations Guide

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.

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.

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.

Pattern Type	Description
Local Directory	Search the List of Devices and List of Services.
Services	Includes aliases, which are searched before the service
	prefix.
DNS Name	Look up a DNS Name
IP Address	Look for an IP addresses in the IPV4 format
Prefix	Look for a prefix specified in the dial rule
Prefix Range	Look for a prefix within the range of prefixes specified in
	the dial rule
