[VoiceOps] Caller-ID: SIP From vs. P-Asserted-Identity

[Ryan Delgrosso]

I have to agree with Alex on this one.

PAI
RPID
 From

Only one matters and they are weighted in that order.

If you need the billing number to be different than the highest 
applicable in the above list, insert a diversion header and be done with 
it (warning not all term carriers properly obey diversion headers but it 
is the most correct answer)
