What is "Transfer Number" feature, whose number it captures, and its use case?

The "Transfer Number" feature captures and stores the phone numbers of parties involved in a call transfer, including customers and agents. This feature is useful especially when a call center transfers calls to a set of predefined numbers and it is easier to store them and select from a list for agents.

For example, a logistics firm has a centralized call center and based on customer requirement they transfer to the nearest branch who will coordinate further.
