P/N 480-0062-00-14 1-12Chapter 1: OverviewAdvanced Features/CapabilitiesCall ManagementThere 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 StaticRoutes.Bypass Directory Numbers. Bypass Directory Numbers (BDN) are telephone numbers that areautomatically routed directly from a line circuit to the PSTN; they will not be routed VoIP. Someexamples of bypass numbers include toll-free calls, emergency calls (i.e., 911), or high securitycalls.Hunt Local Directory Numbers. A Hunt Local Directory Number (Hunt LDN) is a phone numberreachable 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 asLeaky Area Map). A Hop-Off Directory Number is routed over the IP to another Tenor location andthen 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 routeassociates endpoints (as represented by their IP address) with Directory Number patterns.Dial Plan OptionsPublic/Private Dial Plan Support.The Tenor AX supports public and private dial plans. A publicdial plan includes numbers which conform to the international dialing plan (E.164) of a countrycode + city/area code + local number. For a public dial plan, you can define the numbering planstructure for the Tenor AX to use for outgoing calls.A private dial plan does not conform to a public dialing plan (i.e., 3 digit dialing plan); through theTenor AX you are able to configure the unique pattern/dialing plan structure, including numberlength.You are able to configure which dial plan to use for incoming and outgoing calls, including whetherother options such as hop-off calls, will use a public or private dial plan.User Programmable Dial Plan Support. The User Programmable Dial Plan Support (UPDP)enables the Tenor to identify a completely customizable set of digit sequences, such as Local,National, International or Private Numbers.PassThrough support for certain call types. Certain call types can be directly routed to a trunkcircuit, without going IP. There are several routing tables you can configure through the Tenor Con-figuration Manager to adjust how the Tenor AX unit routes these types of “pass through” numbers.For example, you may want to configure 911 as a “bypass number”, which means that all 911 callscoming into Tenor AX from the line circuit will be routed directly to a Trunk circuit presumably con-nected to a PSTN. Bypass calls are never routed over IP.VoIPon www.voipon.co.uk sales@voipon.co.uk Tel: +44 (0)1245 808195 Fax: +44 (0)1245 808299
