# How to Set Up DIDs (Inbound Numbers)

> Register inbound DID numbers from your carrier in Ringingo and map each one to a queue, IVR, or ring group for call handling.

DIDs (Direct Inward Dialling) are virtual telephone numbers assigned to the Ringingo account. When a customer dials a DID number, the platform is receiving the call and routing it according to the configured destination.

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

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

  <Step title="Fill in the fields">
    | Field                 | Description                                                                                                                                                                    |
    | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
    | DID Number (required) | Enter the E.164 format inbound number exactly as provisioned by your carrier (e.g. +97145XXXXXX). This must match the number your carrier sends in the SIP INVITE "To" header. |
    | Status                | Enable to activate the DID for inbound call reception immediately. Disable to register the number without making it live.                                                      |
    | Timeout               | The maximum number of seconds to ring the destination before the call is considered unanswered and forwarded to a failover destination.                                        |
    | Codec                 | The audio codec to use for calls arriving on this DID. PCMA (G.711 A-law) is the default and recommended setting.                                                              |
    | DID as Caller ID      | When set to Yes, the DID number itself is used as the outbound Caller ID for callbacks and transfers initiated by agents handling calls on this DID.                           |
  </Step>

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

<Tip>
  After creating the DID, navigate to the relevant IVR, Ring Group, or Campaign configuration and assign this DID as the routing destination. A DID without a routing destination is accepting the call but has nowhere to send it, resulting in immediate disconnection.
