Locations Affect Dial Plan

Locations are used to restrict or filter access to portions of dial plan entries. The dial plan can be filtered using locations at two levels of entries:

1. Input Pattern  

2. Dial Groups (line groups and dialed numbers)
 

Considerations

If a dial plan entry does not have <All> as Location Filter access then those specific options (patterns or dial groups) are removed from the dial plan and are not presented as dialing choices on dialing lookup in the describe number tool.

Any input pattern that has the <All> as Location Filter may require special care when defining the Dial Groups for the dial plan entry. For example in a 911 pattern, the default line groups specified should be local to the Location. Using 911 call routing makes sure the correct gateway or line is used for stations at a remote site.

Based on how the gateways are set up, locations filters can be used to route what is normally a long distance call over a SIP gateway, treating the call as a local call, avoiding any toll (toll avoidance).
