Blended Voice
What is the benefit of configuring a Blended Voice service versus configuring separate Inbound Voice and Outbound Voice services?
The Blended Voice service type is useful if your contact center has a published phone number for outbound calls that you would then expect to receive inbound calls on. Configuring a Blended Voice service would set the caller ID and callbacks would go into a scenario designed specifically for the service. For reporting purposes, note that tracking would need to be conducted per separate services (i.e., Inbound and Outbound).
