I would think it would only matter if the called party is served by the PSTN network because that's the only time that MOU billing should take place. However, it may be that your service provider doesn't differentiate and just bills you MOU charges based on what you send them so that they're covered just in case it hits the PSTN network.

So if it were me operating whoever your provider is, I would take the diversion as the originating number of the leg in question and bill appropriately, as the PAI/FROM in this case is display only.
That being said, does the provider youre with make a distinction between local/LD? thats relatively archaic these days as the aggregate cost of national termination is so low most stopped caring, it might be worth considering moving to another provider.

Hello voice-ops:
Enterprise admin here.
We just converted from ISDN to SIP (and changed providers) and we're seeing some undesirable billing behavior. I'm hoping I can get some objective feedback from different providers.
If a call comes into our system, and we forward it off-net using the SIP trunks (using either "standard" call forwarding or a call forking/paralleling feature like Avaya's EC500 or Cisco's Single Number Reach), we send the call with the SIP FROM header of the original caller (which is desirable to preserve callerID). We also include a Diversion Header with one of our phone numbers (the original destination of the call).
We're being billed based on the *original* calling number, which sometimes results in long distance charges, even if this leg of the call is local to us. This is particularly onerous if the inbound call is international!
So, the question is- what *should* we be billed on: FROM or DIVERSION.
At one point, the provider indicated that P-Charge-Info was supported, but now backing away from that.
Do we have any recourse (technical or otherwise)?
Thanks.
