Configure Custom Caller ID by Queue within a Default Outbound Whisper Flow

When using Amazon Connect, at the beginning of an outbound call, the default outbound whisper flow is heard. By customizing the default outbound whisper flow to use the corresponding caller ID, organizations enhance their brand recognition, standardization, and identifiability. For example, the Caller ID may vary by corresponding departments or company phone numbers. Customizing the Outbound Whisper Flow enhances the call experience, by ensuring Custom Caller ID, voice, logging, and recording is configured in a standard way for your organization.

This customization enables the use of phone numbers not owned by the Amazon Connect Instance to be used as the Caller ID varying by the Queue.

Caller ID spoofing is a method of getting the telephone network to show the call's recipient a different identity than it originated from.

Use Cases:

Enables use of multiple Caller IDs by separate lines of business without prior porting of the phone numbers. Facilitates differentiations by departments such as Scheduling, Billing, Internal Services, or any line of business that the Caller ID may need to vary for. Allows validation and production level use of the system while forwarding from legacy systems for inbound calls ensuring success before fully porting the phone number while continuing the standard customer-facing caller ID experience.

With the Outbound Whisper flow associated with the queue for the agent placing an outbound call, the resulting caller ID will appear based on the queue. Without porting the number to the Amazon Connect Instance, the outbound call will now have the correct caller ID, should the caller be disconnected and need to call back.

Additionally, using the customized default outbound whisper flow with the Set logging behavior, Set recording and analytics behavior, and Set voice blocks will ensure a standard experience and configuration for all queue’s configured with this default outbound whisper flow.
