Flow types

You can use this block in the following contact flow types:

  • Inbound flow

  • Customer Queue flow

  • Transfer to Agent flow

  • Transfer to Queue flow


Note the following properties:

  • Resume flow after disconnect: This works only if the external party disconnects, and the customer doesn't disconnect. (If the customer disconnects, the whole call disconnects.)

  • Send DTMF: This property is useful to bypass some of the DTMF of the external party. For example, if you know you'll need to press 1, 1, 362 to reach the external party, you can enter that here.

  • Caller ID number: You can choose a number from your instance to appear as the caller ID. This is useful in cases where you want to use a number that's different from the one the flow is actually using to make the call.


    If you are using Amazon Connect outside of the United States, we recommend choosing Caller ID number and then selecting an Amazon Connect number. Otherwise, local regulations may cause telephony providers to block or redirect non-Amazon Connect phone numbers. This will result in service-related events, such as rejected calls, poor audio quality, delay, latency, and displaying the incorrect caller ID.

    In Australia: The caller ID must be an Amazon Connect provided DID (Direct Inward Dialing) phone number. If a toll free number or a number not provided by Amazon Connect is used in the caller ID, local telephony suppliers may reject outbound calls due to local anti-fraud requirements.

  • Caller ID name: You can set a caller ID name, but there's no guarantee it will appear correctly to the customer. For more information, see Why your caller ID might not appear correctly to customers.


When Transfer to phone number block is used without specifying a custom caller ID, the caller ID of the caller is passed as the caller ID. For example, if you transfer to an external number and no custom caller ID is used to specify that the call is coming from your organization, then the contact's caller ID is displayed to the external party.

Configuration tips

  • Submit a service quota increase request requesting that your business be allowed to make outbound calls to the country you specified. If your business is not on the allow list for making the call, it will fail. For more information, see Countries you can call.

  • If the country you want to select is not listed, you can submit a request to add countries you want to transfer calls to using the Amazon Connect service quotas increase form.

  • You can choose to end the flow when the call is transferred, or choose to Resume flow after disconnect, which returns the caller to your instance and resumes the flow after the transferred call ends.
