Similar to the “Display extension name” feature, it may be useful to customize the transmitted phone number. Whether you transmit the original source number or the number of the forwarding extension depends on your specific scenario.

The latter is useful when it is less important who exactly is calling and more important what the original destination of the call is (e.g., a specific hotline). If, on the other hand, you transmit the source number, this has the advantage that calls can be accurately assigned and callbacks are possible.

Attention!

This setting applies only to external call forwarding configured in the Cloud PBX for a user or a resource.
