[VoiceOps] Question about billing on SIP trunks

[Ryan Delgrosso]

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.
