Call Management

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 the 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.

Dial Plan Options

Public/Private Dial Plan Support.The Tenor AX supports public and private dial plans. A public

dial plan includes numbers which conform to the international dialing plan (E.164) of a country

code + city/area code + local number. For a public dial plan, you can define the numbering plan

structure 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 the

Tenor AX you are able to configure the unique pattern/dialing plan structure, including number

length.

You are able to configure which dial plan to use for incoming and outgoing calls, including whether

other 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 trunk

circuit, 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 calls

coming 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.
