I guess it depends on the provider's business model. If the provider 
wants to receive termination fees for incoming calls, then he wont use 
ViPR. If the provider does not care about termination fees, then he can 
allow incoming calls with ViPR, e.g. to save gateway resource.

Anyway, it can use ViPR on outgoing calls to avoid transit costs.
