In call forwarding, there are two legs to each call:
- The inbound leg from the caller to your Plivo number.
- The outbound leg from Plivo to the number you are forwarding the call to.
Each leg is billed separately to your Plivo account on a per-minute basis.
Example: A caller calls a US Plivo number in your account. To receive the call, you will be charged inbound call charge to US. Now, if you are forwarding your call to say Germany, the outbound price for Germany will be applicable.
