Manage SBC Prefixes

This option lets you configure SBC dial plans for specific sites. SBC prefixes can be configured manually or can be imported from a CSV or text file. A tag can be applied to each entry to associate the prefixes to a specific SBC site location (SIP Connection). The dial plan rule does not have a unique name and instead inherits the name of the configured dialplan e.g. 'CustDialPlan'. In the CLI script, the shortname of the customer is used to match the prefix to the customer tenant. In the Dialplan configured on the SBC device, the Dial plan rule name inherits this shortname.

This tag may be one of the following values:

The derived Trunk FQDN of the SBC device. Used predominantly for Direct Routing customers.
The Tenant's Azure subscription ID. Used predominantly for Operator Connect customers.

The dialplan rule does not have a unique name and instead inherits the name of the configured dialplan ‘CustDialPlan’. In the CLI script, the shortname of the customer is used to match the prefix to the customer tenant and in the Dialplan configured on the SBC device, the Dial plan rule name inherits this shortname.

5. Do one of the following:
Manually add telephone number prefixes and then click . Enter + prefix for each number that you wish to configure.

The number is displayed in the prefix list.
