Inbound Permissions

Inbound Permissions allow you to control how inbound calls are handled based on Caller ID patterns. You can define rules to allow or deny calls from specific callers before they reach any routing logic.

Enabling Inbound Permissions

Inbound Permissions checking is disabled by default to avoid unnecessary overhead during call processing. When disabled, a warning banner is displayed on the Inbound Permissions screen.

To enable checking, set the Dialplan Variable TL_CHECK_INBOUND_PERMISSIONS to 1. Setting it to 0 or removing the variable disables checking.

Note

In addition to system-wide permissions, Inbound Permissions can be configured on a per-tenant level. System-wide permissions have higher priority and are checked first. Tenant-level permissions are only checked if the call passes the system-wide check.

Description. A short description of the rule.

Caller ID Pattern(s). A number or pattern to match inbound caller IDs. Accepts multiple values separated by a comma. Prefix a pattern with _ to use dialplan pattern matching:

• X — matches any digit 0-9
• Z — matches any digit 1-9
• N — matches any digit 2-9
• [13-5] — matches any digit in the brackets
• . — matches one or more characters

Action. What to do when a caller ID matches the pattern:

• Deny — reject the call
• Allow — let the call through
