Thanks. Let me a question about this forwardings and accounting since I'm 
designng it just now and have a doubt:

The gateway will be in fact other OpenSer+CDRtool+MediaProxy (if I can 
configure it) or Asterisk. They will contact with the real SIP carrier.

So when user_B at domain_B calls sip:12345 at domain_B it will appear in OpenSer 
gateway:
- From=user_B at domain_B
- RURI=12345 at domain_B

But in the aboved explained forwarding it will appear
- From=user_A at domain_A
- RURI=12345 at domain_B

I'm not sure then how to invoice this call. I see 2 options:

a) Invoice always based on RURI [*]

b) Add a "Diversion" (or other custom) header in main OpenSer so OpenSer 
gateway will invoice to the user in that header.


I need to think long time about it, but I'd like to know opinions about it.


Really thanks a lot for your help.
