[Serusers] Billing info/Remote-Party-Id on forwarded calls

[Tor Setane]

Hi,

User 1000 calls 1001, who is cfwd (302) to a pstn number. Pstn provider will see 1000 as the caller and he get billed 
for the call to pstn. Is there a way to insert 1001 in the Remote-Party-Id header in this scenario to fix billing info?

Something like: if (method == "30X"), extract number from "To: header" and insert it as Remote-Party-Id?

Thanks,
Tor.
