We show that the prediction of a strategic connectivity breakdown under a receiving-party-pays (RPP) system and discrimination between on- and off-net prices does not hold up once more than two networks are considered. Indeed, equilibria with finite call and receiving prices exist for a large and realistic range of call externality values. This allows regulation of termination rates to achieve the socially optimal retail pricing structure under RPP.
