Abstract:
1. A method comprising: providing, for each of a plurality of geographic service areas of a communication network, at least one discrete call facilitation platform wherein each discrete call facilitation platform has at least one corresponding routing address and supports at least one corresponding end-user station; providing a plurality of gateways to interface the discrete call facilitation platforms to another communication network wherein each of the plurality of gateways has at least one corresponding routing address; providing routing addresses as correspond to each of the discrete call facilitation platforms to at least some of the plurality of gateways, such that at least one of the plurality of gateways is able to specifically address a communication via any of the discrete call facilitation platforms; providing at least one routing address as corresponds to at least one of the plurality of gateways to each of the discrete call facilitation platforms while denying at least one of the discrete call facilitation platforms of information regarding routing addresses for at least one of the plurality of gateways comprises providing varying ones of the discrete call facilitation platforms with differing gateway routing addresses from the database; providing a database containing all of the routing addresses for the plurality of gateways and all of the discrete call facilitation platforms; such that all of the discrete call facilitation platforms do not share a common view of available gateway routing addresses.
