What about this scenario?

User A calls User B. User A and User B are registered on the same Asterisk system.
User B does an attended transfer, and transfers the call to user C, who is registered on a different asterisk system.
You set the accountcode to be user B's account code, as user B will be responsible and billed for this call leg.
You then do a DUNDi lookup, and get an IAX path to user C on the second asterisk system.
You dial user C. At this point, no account code was passed with IAX between the two Asterisk systems.
How can user B be billed for the call???
