In my view, that depends on what is doing the forwarding.
If it's the customer handset actually initiating the forward, then it
should just look like a normal termination call from the customer.
If it's a multi-tenant switch or other call control agent, it should
have some way of associating forwarded calls with an account and
sticking an account ID or similar into the CDRs, which will reveal who
to bill and presumably the rate plan to use.
If it can't do that, the product sucks.
