    • E164 is required for SMS on 3CX

    Name your Rule: Example: Tyler Direct

    Select your DID: Example: +1558675309

    • The DIDs in drop down are the DIDs that are set up in your SIP trunk, please go check out the guides below on adding numbers to your SIP trunk.

    Select your routing for both during and out of office hours.

    Specific office hours can be configured per inbound rule or if set in the PBX settings. They are global for all rules unless overridden here.


    Configure CID Rules

    1. Select + Add CID Rule

    CID rules control how incoming caller IDs are routed.

    2. Configure CID Rule: Block incoming calls

    Example shows how to block a caller ID.

    Name your Rule: Example: Block

    Enter the caller ID: Example: *2145551234

    • The * is a wildcard on 3CX, anything matching the * will be matched to the rule.

    Select your Trunk: Voxtelesys

    Route your calls to: End Call

    In this example, all calls from +12145555000, 12145555000, or 2145555000 on trunk 10000 Voxtelesys will be blocked.

    3. Configure CID Rule: Specific Route

    Example shows how to force all calls from 2145555000 to route to extension 3006.

    Name your Rule: Example: Route to Tyler

    Enter the caller ID: Example: *2145555000

    • The * is a wildcard on 3CX anything, matching the * will be matched to the rule.

    Select your Trunk

    Route your calls to: Extension 3006

    In this example, all calls from +12145555000, 12145555000, or 2145555000 on trunk 10000 Voxtelesys will override any inbound rule and route to extension 3006.
