# How to Create Outgoing Rules

> Route outbound calls in Ringingo to the correct SIP trunks with number manipulation, prefixes, and destination-based matching.

Outgoing Rules are routing policies that link campaigns and user groups to specific SIP trunks. When a call is placed, the system is evaluating the outgoing rule to determine which SIP trunk to use and how to handle number prefixes.

<Steps>
  <Step title="Navigate to Outgoing Rules">
    Go to **Outgoing Rules → Outgoing Rules** in the left sidebar menu.
  </Step>

  <Step title="Create a new Outgoing Rule">
    Click **+ Create Outgoing Rule**.
  </Step>

  <Step title="Fill in the fields">
    | Field           | Description                                                                                                         |
    | --------------- | ------------------------------------------------------------------------------------------------------------------- |
    | Name (required) | A unique label for this rule (e.g. "JT-UAE-OutboundRule"). Appears in campaign and user group assignment dropdowns. |
    | Description     | Optional internal notes describing the purpose of this rule.                                                        |
    | Status          | Enable to make the rule available for assignment immediately.                                                       |
  </Step>

  <Step title="Configure Extension manipulation">
    | Field            | Description                                                                                                                                                               |
    | ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
    | Length           | The expected digit length of the dialled number. Set to 0 to match any length.                                                                                            |
    | Prefix           | A digit string that the dialled number must start with to match this rule. Leave blank to match all numbers.                                                              |
    | Strip            | The number of digits to remove from the start of the dialled number before sending it to the trunk (e.g. strip 0 from a local number to convert to international format). |
    | Prepend          | Digits to add to the start of the dialled number after stripping (e.g. prepend 971 to add a UAE country code).                                                            |
    | Trunk (required) | The primary SIP trunk through which matching calls are routed.                                                                                                            |
    | Failover Trunk 1 | A backup trunk used automatically if the primary trunk is unavailable. Critical for high-availability deployments.                                                        |
    | Failover Trunk 2 | A secondary failover trunk if both the primary and Failover 1 are unavailable.                                                                                            |
  </Step>

  <Step title="Save the rule">
    Click **Save**.
  </Step>
</Steps>

<Warning>
  Every campaign (Inbound, Outbound, and Blended) requires an active Outgoing Rule to be assigned before it can be saved and activated. Without a valid outgoing rule, the campaign cannot place or receive routed calls.
</Warning>

<Tip>
  Always configure at least one Failover Trunk for production outgoing rules. If the primary trunk goes offline due to a carrier outage, failover ensures calls continue routing through the backup trunk without manual intervention.
