Term Definition
Off-Net Not served, or not able to be served, using a given service provider’s facilities. A call originating (or terminating) off-net has originated (or terminated), not on the network managed directly by the subscriber’s service provider, but on another service provider’s network. The latter provider usually bills the former provider for roaming or for service resale on a wholesale basis; the subscriber’s provider, in turn, usually bills the end user on a retail basis.
On-Net Served, or able to be served, using a given service provider’s facilities. A call originating (or terminating) on-net has originated (or terminated) on the subscriber’s service provider’s managed network.
Origination Refers to calls that originate in the PSTN public switched telephone network and are carried to their destination over the Internet. Telephone communication networks use various theories on multi-paneled circuitry integration, network distance reduction algorithms, switch theory, chaos non-linear dynamics, randomized multi-processed information, game theory, and wave-particle theorem of mass and energy stability over various virtual static networks, to implement origination. The topic is often considered to be the most complex matter in VOIP, as it is vital to the integration and maximization of potential between the broadband connections, and telecommunication wires.
