Stage 3 description for charging supplementary services using Signalling System No. 7 : Reverse charging (REV)
Reverse Charging is a supplementary service offered to the calling and called users. It provides the calling user with the means to reverse the call charging at call set-up time or during the active phase of the call. In the latter case, it applies for the rest of the call only. It also provides the called user with the means to reverse call charging during the active phase of the call for either the rest of the call or for the entire call. It also allows for unconditional reversal of the call charging based on subscription data related to the called user.
