But imagine this case:

- domain_A and domain_B are hosted in my OpenSer (but totally independents).

- sip:user_A at domain_A calls sip:user_B at domain_B

- In OpenSer there is forwarding:  sip:user_B at domain_B -> sip:012345 at domain_B

- In domain_B permissions table I allow forwardings to PSTN for calls made 
from others domain (as domain_A), but not direct INVITE's (of course).

- Finally sip:user_A at domain_A calls sip:012345 at domain_B but I know in OpenSer 
it's a allowed forwarding so add any header (Diversion?) the gateway to know 
it and facture to sip:user_B at domain_B isntead of sip:user_A at domain_A.

- In fact, in the gateway I will facture based on RURI instead of "From".


Is not correct?
