[VoiceOps] VNXX

V-NXX is mainly a conflict for Inter-LATA numbers.
ILEC's can give you V-NXX inside the LATA with services like Extended 
PRI and RCF, but ILEC's still have that LATA issue and mindset.
So when L3 or GPOPs start giving out state-wide PRI's, that's when the 
ILEC's start screaming.
It all comes down to the money - Inter-Carrier Compensation.

V-NXX is mainly Inbound traffic, which means that the ILEC's are paying. 
They never like that.

That's the main problem.
