Routing Table Options
There are four types of routing databases you can configure: Bypass Directory Numbers (BPN),
Hunt Local Directory Numbers (Hunt LDN), Hop-Off Directory Numbers (HDN) and Static Routes.
Bypass Directory Numbers. Bypass Directory Numbers (BDN) are telephone numbers that are
automatically routed directly from a line circuit to a trunk circuit (PSTN); they will not be routed
VoIP. Some examples of bypass numbers include toll-free calls, emergency calls (i.e., 911), or high
security calls.
Hunt Local Directory Numbers. A Hunt Local Directory Number (Hunt LDN) is a phone number
reachable through local Line Circuits.
Hop-Off Directory Number. A Hop-off PBX call travels over IP, and then “hops” off into the pub-
lic network (PSTN) on the distant side to reduce or eliminate public toll charges (also known as
Leaky Area Map). A Hop-Off Directory Number is routed over the IP to another Tenor location and
then out to the Trunk circuit, possibly to the PSTN as a local call.
Static Routes. Static Routes are used between networks and other H.323 devices that are not regis-
tered to the network through the Border Element (such as non-Quintum gateways). A static route
associates endpoints (as represented by their IP address) with Directory Number patterns.
